Up to a point. I mean, if the other person is screaming and swearing at me - yeah I'm going to too but if the other person is trying to be polite and if it's someone I don't really know well then yeah I would try to be polite. I'm quite calm so if I start to argue with あなた that means I'm pretty damn pissed.
Eye for an eye. Tooth for a tooth. Polite response to a polite statement. Rude one to a rude one. But I ain't really adept at trash talk so rudeness may only be in a a form of slur. There are also some instances I may deem not worth answering または that the other person's statement is just too retarded または nonsensical I'd rather not match the idiocy.
