To completely miss the point, I mean - there are answers to all of those questions: yes, no, and if you have both you're a classic transsexual, in the original MEDICAL sense of the original MEDICAL use of the term, which is not how the word is usually used these days (which is to say, incorrectly, like all colloquialisms - eg No, that shit's not hot, it's not cool either, it's just bad! - neither of those words are used in their technically correct sense). None of these are gotchyas or even significant in the "debate" which is entirely hysteria in the first place, sex simply does not matter this much and everyone is always free to do whatever they want, and to find likeminded individuals, and that the media has chosen to flap its jaw about it is something we all should deal with by turning them THE FUCK OFF and allowing the gibbering monkeys to have no impact on our consciousness.
That said this is the first time I've ever seen Elon make a delicate suggestion, which is kinda nice.
