Is it normal to play ignorance to avoid conflict?
You can spend your time getting angry at someone who pointlessly insult you to get a rise. However a lot of times this is not very tactful and ends up making you look very bad.
So sometimes I simply pretend not to get the insult. Example:Attacker:"I sucked your moms cock". Me:"Gee, I was not aware that women had cocks to suck. You should take a biology lesson sometime."
However sometimes this does not always work if the second party is insistent and keeps ranting you did something wrong. Even if you keep denying it. It seems to work with most conflicts though.
