I see nothing wrong with cross-gender roleplayers, I'm one actually. When I first began to play Feralheart I always roleplayed with male characters, still do. I also have female characters which I also use in Feralheart. There's no point getting mad at cross-gender roleplayers because isn't that what roleplay is? Being someone you're not. Roleplay isn't sticking to one gender for the whole time, it's being different to who you are. It does not mean that roleplayer wants to be the opposite gender in real life, it doesn't mean that they are homosexual. Just relax and stop assuming so and that way both roleplayers can enjoy themselves. No one wants to put up with that annoyance when you are screamed at for roleplaying like this. In fact, there are lots of people who do this on tv shows, plays, performances and movies yet no one is complaining.
Short: There's nothing wrong with cross-gender roleplaying c:
