I used to not retaliate but now I have started to.

I do the rational thing depending on the circumstances, argue their points with common sense, factual evidence and relevant information.
If they're just being a pain in the ass though and just criticizing or trying to start an argument with me for the heck of it or because they have a chip on their shoulder. I'll end them, plain and simple.1

Break their argument down calmly, outwit them. If that just upsets them more then I just get up and leave, refusing to acknowledge what they have to say until they calm down.
I only take criticism if I think the person has a point, otherwise it means nothing to me.1
