There's probably more people like you on the forum than this 'image' you are thinking of, of lots of semi fem guys all flouncing about 24/7 calling each other Julie and Karon.
I haven't dressed up for months and can't be bothered but I enjoy the forum from a social aspect.
But as all this dressing up business is a bit confusing anyway, there is a general politeness (I can't spell etiquet ettiquette) about keeping the pretence and adopting a name and personal pronouns to match.
It's not so much that people really do believe they are this person or that personality. It's just a convention; a short hand; a way of all speaking the same confused language without offending anyone.
Think of it like going to a Klingon convention and calling someone Kevin when they clearly state on their name badge that they are WarkVaard. It's just being polite and joining in the pretense.
