Within the USA non-Europeans suffer detrimental bias based upon race.
Now I can argue that there is only one race, the human race. We are far more similar than different, but we humans do have external markers of colour. This affects our eyes, hair and skin, then we have differing shapes too.
Racism has existed for all of recorded history, and likely much, much longer. During the nineteenth century white European scientists began to categorise people by race. At the time, it appeared to be logical and scientific. The eugenics movement began in the UK and rapidly caught on in Germany and the USA where it remained popular beyond WWII. Only with the rise of the Civil Rights movement did it finally begin to be debunked. However, the ideas still remain entrenched with some fuckwits.
In a weeks time, I will be writing a short sociology paper on the subject of racism in the UK.
