Yep. All groups have prejudice. The difference is racism is prejudice in the particular people who enjoy an ethnic social advantage. So it will look different in different societies.

There is a difference between prejudice and racism. The former is the manifestation of individuals acting against other individuals, the latter is where it is institutionalized in policies and laws. I believe you are conflating the two concepts.

@MikeInBatonRouge Not really, racism comes from up to down and vice versa, hate due to ignorance, comes in all colors against other colors and all shades, not one single race is exempt because ignorance affects all humans.

@Mofo1953 What redbai just said.
Racism is a particular subset of racial prejudice. Social advantage and privilege are key elements to racism.

@MikeInBatonRouge I disagree, I have been to many very poor countries, remember the Hutus and the Tutsis from Rwanda, they hated and killed each other because of racism, most were poor, few were privileged, but all hated each other and genocide happened.

@Mofo1953 There is a difference between a bare-bones basic definition and a fleshed out social science definition, and it seems that now even the people at the Merriam Webster Dictionary agree it needs to reflect the role of systemic power imbalances.

Other sources also recognize the role of societal power differentials among differing ethnicities considered "races." An individual can espouse racist views, agreed. It becomes significant when those views are backed up by societal institutions and conventions that have the power to marginalize and harm the targeted group(s).

You are certainly right that racism "can" be defined in simple terms of individual prejudice and conduct, but sociologically that is woefully inadequate, as explained in the opening of this Harvard research paper. I dare say we sociology background types know what the fuck whereof we speak a smidge better than dictionary editors. And now Wevster has concurred.

Abstract
The sociology of racism is the study of the relationship between racism, racial discrimination, and racial inequality. While
past scholarship emphasized overtly racist attitudes and policies, contemporary sociology considers racism as individual- and
group-level processes and structures that are implicated in the reproduction of racial inequality in diffuse and often subtle
ways. Although some social scientists decry this conceptual broadening, most agree that a multivalent approach to the study
of racism is at once socially important and analytically useful for understanding the persistence of racial inequality in
a purportedly ‘postracial’ society.
At root, racism is “an ideology of racial domination” (Wilson,
1999: p. 14) in which the presumed biological or cultural
superiority of one or more racial groups is used to justify or
prescribe the inferior treatment or social position(s) of other
racial groups. Through the process of racialization (see Section
Racism as a Social Process), perceived patterns of physical
difference – such as skin color or eye shape – are used to
differentiate groups of people, thereby constituting them as
‘races’; racialization becomes racism when it involves the
hierarchical and socially consequential valuation of racial
groups.
Racism is analytically distinct from racial discrimination
and racial inequality. Racial discrimination concerns the
unequal treatment of races, whereas racial inequality concerns
unequal outcomes (in income, education, health, etc.). While
racism is often implicated in both processes, contemporary
racial inequalities and forms of discrimination are not always
the immediate result of contemporary racism (Pager and
Shepherd, 2008). The sociology of racism investigates the
relationships between these three phenomena, asking when,
how, why, and to what extent they reproduce one another. In
the post-Civil Rights era, with (overt) racism now widely condemned, one challenge for social scientists is to conceptualize
and measure its more subtle and diffuse manifestations and
lasting effects.

@MikeInBatonRouge Way too long and boring, I don't need sociologists telling me what I witnessed in person and in situ, these people don't "espouse racist views" they kill and maim for their ignorance. My witnessing these atrocities, again in person and in situ, tells me that my experiences weigh so much more than what a Harvard, BBC or any other sociological paper or writing purports.

@Mofo1953 still bad, horrible, devistating, but another term: Ethnic hatred. Rather similar to Serbia and Bosnia.

@MikeInBatonRouge Ethnic hatred IS racism, give it up dude, you're trying to defend what you said by ridiculous nit picking. Croatia, Serbia and Bosnia was religious intolerance between orthodox catholics, roman catholics and muslims. Nothing to do with ethnias as they were all Slavs.

@Mofo1953 you just admitted to not really digesting that "too long and boring" article to consider its validity. It only appears to be nitpicking to you because the effort to explain the point to someone already dismissive of it gets labored. The point is still valid.

Everyone has prejudices due to our limits or experience and perspective. The key factor in how dangerous racial prejudice becomes is the degree of societal marginalization the target group has to contend with, which is related to social power disperities.

If you have whole ethnic groups slaughtering other ethnic groups, it does not rule out the prospect that racism is a factor, but it could be straight up ethnic hate, competition for control if land or other limited resources. Would you call the Hatfields and McCoys family feud racism? No. But they hated each other and kept killing. Tribalism is not necessarily racism.

@MikeInBatonRouge Give it up dude, can you understand that? First of all I read all your excessively lengthy post and links, and I ratify my assessment, too long and boring. Your insistence in trying to save your original dumb point is now bordering on ridiculous and obsessive, your examples are risible, dumb and also wrong, make no sense. So let me clarify this once again for you to understand why you should stop trying to justify your original comments that were not accurate: nonsense trying to be backed up with nonsense is still nonsense. Period. Now take a chill pill and admit that pride will get you nowhere. Just stop so your embarrassing points to rationalize racism and hatred are going nowhere. No simulation or internet article will ever supersede witnessing something in person and in the place it happened. Even a court of law accepts this, but not you.

@Mofo1953 Really? No, really? You are now defending the wisdom and reliability of the courts? Eye witness testimony is notoriously unreliable, and yet eye witnesses are often exceedingly confident they are right. YOU might have a very solid recollection of what you witnessed over the years and yet still jump to conclusions as to motivations behind those actions. (Since you appreciate my social science references so much, here's another. You're welcome!

We need to remind ourselves there are more than one definition for racism, or haven't you noticed dictionaries often list 2, 3, or more definitions?
You are right that racism is racial prejudice.
It is ALSO a structural, systemic social problem, aka "institutionalized racism," and it is that second definition the original poster was clearly applying.

I never said only Whites can be racist. I never even implied it. Not sure how you took it. What I was trying to say was the difference between one person's prejudice and another's is the difference in how much damage can be done by some people's prejudice enjoying the benefit of societal institutions that back them up. In America, Whites very clearly enjoy that advantage.

Oh, and as for my "original dumb point" and "Now take a chill pill and admit that pride will get you nowhere,"
I suggest for you a glance in the mirror.

@MikeInBatonRouge There you go again, now even courts of law are crap to you. Amazing. Let's see if you get this: fuck off, stop being such an ass in reality and in the mirror too, knowing your propensity for not letting go and having the last word regardless of how moronic that word may be, I will start the countdown til your next inane posting.

Yes, but I am sure it is not true.

@Jolanta I didn't verify, just gave attribution! I could have equally said that many women wished that they could see unicorns!

You know I know Bourbon, and it's hard to imagine that. But, those people likely don't think of those kids as black, or think they aren't like "other" black people. People think they can't be racist because they have black friends, or black grandkids or they once dated a black person. Thomas Jefferson had kids with a black woman but still thought they could be owned by white people.

@JonnaBononna Then people can be so hateful. I had a black wife and we had no kids. Someone i know said she wished we did have kids so my wife and I could divorce and she would "take them kids away from me." WTF is that?

@DenoPenno Jesus fucking christ on a stick..... I hate people sometimes

Not all white people suck.

@xenoview where's that eyeroll emoji? You sound like the "all lives matter" crowd.

@xenoview Suffice to say white people are the cause of most of the ills of the world, and too many are either denying their ill gotten privilege or are actively working to keep it

@JonnaBononna here ya go

They do suck, and I’m white.....ashamed to be white, but white nonetheless.....
