I usually give my palm for them to talk with. LOL

Easy. Ask them to validate anything that doesnt make sense. In my experience people whom like to argue never have scienitific backing for their claim or theory. So when its clarified as a claim, statement, or theory, there lies no reason to argue.

Walk away. I don't like argue

Argument and verbal conflict are two different forms of dscourse. The former is a logical approach to settling different viewpoints on a subject, while the latter is most often unproductive and can lead to violence and loss of friendship. The best way to settle the latter is simply to agree and refuse to pursue it further. There are, of course, people who begin arguments for the sole purpose of creating a situation in which they attempt to visit violence or other unfortunate behavior upon the other person. Those people will often not be dissuaded, so it isbest simply not to have anything to do with such individuals.

You don't...

Arguing is useful at times, but some people are just turned on by conflict. They are usually far more troublesome than they are worth, and I try to present them with an air of indifference when I think they are just arguing for the hell of it. Or I try to zing them with a comment they can't match if that will cool them off. When there's really something to decide, arguing is OK, but otherwise it's a waste of time.

I don't, I walk away. I'm perfectly fine with them having the last word. And usually this pisses people off which gives me some satisfaction.

I don't.
I have a sister who I barely speak to, and making a conscious decision to stay away from her has brought a lot of peace to my life.

You always agree with them

I try to win as many arguments with them that I can. That sometimes discourages them.

I love to argue but only with like minded people. If an argument gets personal or ugly, I bail.

Anymore, this sums it up.

I disagree with the premise of this post. Let us discuss this ad nauseam.

Ask them what it is that they really want! Or just ignore them and walk off

I don't.

Well I'm someone who likes to argue, so if you don't want to argue with me I'd suggest just not responding. It would piss me off personally but eventually I would wander off to yell at someone on the internet or to grumble to myself while cleaning dishes.

One diversion technique is the anknowledgement and the validation of the other person's emotions. "You look angry."

Depends on who it is, usually i just avoid them and walk away

I keep asking why until they get tired of talking. lol

I believe what I believe and I do not have to justify myself to anyone...

Mostly I avoid them. With a personal relationship, family or friend I like to keep it as a conversation/ discussion but sometimes it can escalate to an argument, in that case, I just try to end it and if necessary walk away. If I feel responsible for the escalation, I will apologize. But there are some hot topics that I will just plain avoid.

I just want to be good listener but I sometimes don’t want to argue with someone who makes unworthy arguments,which are unsupported facts. I try to avoid this peaceful.

I assume you refer to people who get off on arguing or being contrary. Mostly I don't interact with such people, unless forced to by circumstances such as work, or unfortunate family obligations. Which is not to say that I necessarily avoid them, it's just that they get no traction with me as I'm not impressed with their bullshit.

I avoid them

First actually understand and identify what the argument is. Then establish the facts to see the truth and then use those to create points to argue for the reallity of the situation!
