What I've learnt is that whoever you are, when you're having a good time being whoever you are, then no stereotyper nor anti-stereotyper can ever put you down.
The way I look at the whole thing girl / boy thing, is that it's like a game. You can do the wrong things, ie be a brash, aggressive, violent jerk or a pathetic, weak mummy's boy and lose the game. Or you can do the right things and get better in the game .
