and to address the "it's the same logic" thing. I'm only going to do this once, because it's very clearly a bad faith argument, but let's get it out of the way.
it is, like many transphobic attacks, a slightly (if at all) repackaged retread of homophobic attacks previously deployed against gay marriage, legalization of non-heterosexual sex and relationships, and more broadly/loosely social acceptance of queer people, i.e. "if we let gay people marry each other then next we'll be letting people marry dogs, children, etc". which obviously hasn't happened, because it was nonsense then and it's nonsense now.
the logic is not the same. everyone here surely understands the difference - which is why it's a bad faith argument - between sex and gender. if you look upthread somewhere we do not get into the nuance of biological sex - i.e. not everyone is born XX or XY - but clearly it exists as an immutable (well, until science discovers a way to make it mutable) fact. whereas gender is a social construct, something so obvious as to be self-evident if you do even a cursory examination of the enormous range and variety of ways in which gender has been expressed in different cultures across human history. that all humans are human is also a biological fact. having said that, I don't really care if someone says "I'm a cat", but they shouldn't expect a level of accomodation for that self-identification - and indeed, it doesn't exist. there is no equivalent of gender-affirming care to become a cat. and there is no school anywhere that has a litter box for a self-identified cat to use. but it's an excellent RW talking point for unscrupulous politicians and social media grifters who dgaf about the truth bc unlike here, there are probably many people out there who don't understand the difference between sex and gender, just as there were (and still are, if less) people who thought gay marriage would cause the downfall of society for...reasons. and it should be treated just as seriously as it deserves, i.e. not at all.
