Anon I've been thinking the same thing. Especially since I'm already left leaning, as someone who is bi and generally against xenophobia. I don't like the idea of shitting on people who have a disadvantage in life, and I'm honestly still conflicted about how I feel about this issue, but so much of it is contradictory and offputting.
I've wondered why men identifying as women has become so socially acceptable in liberal/leftist spaces when Rachel Dolezal was crucified a few years ago for doing something similar and I've come to two conclusions:
1) Other races wouldn't put up with this shit, while women are constantly expected to be comforting and accepting/passive.
2) Piggybacking off of lgb rights. I know that trans people in America fought alongside gays during the Stonewall Riots/AIDS epidemic, but it was commonly accepted back then that they were "men wanting to become female" or vice versa, not "i've always been a woman my male body is actually female". Even feminists in the second wave back then agreed that they weren't women while fighting for their own rights in the workforce. Anyways, with the ruling of gay marriages becoming accepted and overtime gay people becoming more accepted, trans stuff was inevitable.
I'm wondering what America will look like in 15 years, things are getting interesting.
