I have been called worse than the opposite gender in online gaming chats.
Words can not express the stupidity on display by that person lol.
It still doesn't mean anything
I've been doing it for over 20 years, but I am not a woman.
A woman (or a man, or whatever there might be in between) does only exists if it actually exists.
It doesn't exist on the fact that someone said "I am (such and such)"
