I do think Kuzzy makes a valid point though.
While I agree, that entering into that field one is subjected to ridicule, it does become quite absurd when they're outright mocked or called over weight etc.
I think it has to do moreso with people who are just screen names critiquing. When my friends critique a girl I can critique them too because well, I see them physically and it becomes far more of a joke eventually. Here, it becomes something different. I don't physically see everyone and the comments here take on a different tone, at least for myself.
I personally stay out of the threads because I know if something happens there are other mods in there, but right now, I agree with Kuzzy.
