You do your job for hours every week, it is undoubtedly part of you. Calling somebody that is very personal and rude. I'm shocked that there are this many people who don't find issue with it. It removes any kindness from the post and turns it all up to 11. I's deeply personal.
Do some of you really talk to others like this and find no issue with it? It's hard to say words like that and not end up with deep schisms and hatred.
