I've only been on MN a few weeks but I've been really surprised at the language and 'verbal' abuse on some of the threads. Tonight, I read an AIBU, for example, where a post was just a one line insult - no explanation or other comment given. I know AIBU is supposed to be the place where people ask for and get honest answers but some of these insults seem pretty unpleasant, especially where the OP makes it clear they are just seeking an opinion on whether their POV is reasonable.
My current thinking is that I only say here on MN what I would feel comfortable saying to another person face to face. AIBU?
