Calling someone a 'Mentaller' is not insulting and an example of personal abuse?
A 'little light hearted interjection'? It was a nasty, snidey comment which attempted to ridicule me for the amusement of others. I wasn't going to stand for that.
'assuming he acts the same way in every day life, he is clearly one to avoid' Haha, how can you make assumptions about somebody when you don't know the first thing about them! Again, this is a personal attack.
It's also disrespectful to talk about somebody as if they're not there.
You come across as a bully which is nothing to be proud of. Of course though it's not bullying, it's just 'banter'!
