I think there are differing types of this. The offensive type where someone goes out of their way to think of a confrontation of a post they see. And the defensive type where one sees an offputting post or post they irk at and they confront the poster to call them out on it. I don't really find any coping with either, but I do time to time do the defensive type. Especially with trolls. And I guess trolls usually will be doing the offensive type.
Enjoy any good things, even the little and menial ones, as you will never know what impending distresses could descend upon you in a moment.
