So many identities these days... The way I stand is the following: if people want to behave in a certain way, then by all means let them. Just because you're born male it doesn't mean you need to act like a typical male does, and vice versa. But what grates me is why people insist so much on having new identities for every single slight variance that we come across, I don't know why some people are so averse to accepting what biological sex they are. Just because you don't want to behave like a male, it doesn't mean you aren't one. But if you don't want to act like one then great - don't! So for this example, I don't see what the problem is with saying "I'm a female who sometimes behaves like a male", rather than "I'm not a male or female". It doesn't mean people will be more or less accepting, or that you have to change your behaviour, it's just acknowledging basic biology (biology that doesn't have to dictate the way you behave). If you want me to call you "he" then that's fine, of course I will, but that's far away from actually being a male, and there isn't any problem with that, I wouldn't judge you any differently either way.
