I'm sorry, who are you? Did I ask for any permission? No one is entitled to say what anyone, including myself, are allowed to do. If I want to transition, it's because I'm unhappy in the body I came as, and I'd like to end the unhappiness, and finally become the person I've always wanted to be since a little kid. There are kids out there who are terrified to speak out, because people like you hold them back. But I want to be that one person who let's them know it's ok. And if that means being a bitch to the people who say I can't be a girl, then so be it.
