Good. If you've got a penis you're a man. A vagina then you're a woman.
That's quite extreme, K. Perhaps it is a vote winner.
I'm of the opinion that trans people should be allowed to live as they see fit and we should accept them as whatever they want to be. I can't see any benefit to denying someone to live their life as the opposite sex if they want to. Live and let live I reckon.
At the same time, there's a pragmatism needed by all sides in that you can't physically change someone from one sex to another. For that reason, I'm uneasy about trans women winning athletics medals and there are various, usually hypothetical (so fairly irrelevant) circumstances where I feel that way too.
I also find the trans rights crowd a pretty awful bunch who'll close down discussions rather than face certain realities of their arguments. I'm pro trans rights, but would no-doubt be described as a TERF since I don't subscribe to their black or white worldview.
