Even then, chromosomes are just one (1) component of sex development— it is not the sole component. They don’t really matter all that much. Hormones contribute a LOT more. And those absolutely can be changed! 😈 (Not that you NEED to be on HRT to be trans, of course! But the “your chromosomes ___” bullshit doesn’t hold up.)
Maybe I’ll get karyotyped. But even though they may be diffrent my point is that it’s stupid that conservatives want us to be upset about small unchangable things about the sex we’re born as, instead of realising that being trans is about being happy in yourself and your presentation
