Actually, I think if I'd been assigned female at birth, I would have been a very different person. The years of living as male were horrible, but dealing with that has given me a depth of understanding about myself and even (to some extent) other people that I don't think I would have had if I'd grown up in a role more compatible with my nature. There's stuff I see that my cis friends, even the more insightfull ones, don't see. (Of course, sometimes that reinforces my feeling that I'm not really human 🙁 )
