It has nothing to do with power. Just because modern medicine has made it possible to do some sick things doesn't make it right or smart. I include Botox in that as well as changing sexes.
Oh please; it has EVERYTHING to do with power. Power, the 'submission' of a 'man' to someone else.
Since being Trans has been a thing since the dawn of humans, it has nothing to do with 'modern medicine'. The only thing that does, it it should give people the opportunity to either appear more like they should, or fix the screw ups of nature to be more in line with who they are. Before 'modern medicine', they were stuck with how they were which, well, I'm sure you know that story.
But that's one thing you won't really convince me on, that this isn't about power. Because straight men freaking out over Trans people is exactly like their freak out over gay men.
And as I said, women are WORSE than any homophobic/anti-trans moron could ever imagine. For women, it's a betrayal of "Self", not just about power though there is that too.
