This is a silly take. The point is not to compare someone to something they hate, as if that is an insult in itself, to propagate their hate. The point also not to say that things that affirm the gender of cis people is the exactly the same as trans care. The point is the hypocrisy. The point is that their hate is baseless and irrational and they often share more in common with those they hate than they will even acknowledge. They don’t have to be hypocrites for their hatred to be irrational bigoted, but when they are, it make it all the more apparent and easily seen as egregious. There is value in highlighting the hypocrisy and those commonalities for them and others to see, and in normalizing things that affirm ones gender identity, cis, trans or otherwise. Why are we pretending that pointing out those things is somehow a microaggression against trans people or a sign of sharing in that bigotry?
For a much less loaded comparative example, If someone made fun of someone for liking comic books while wearing a batman/punisher tee shirt, you aren’t shitting on comic book fans by pointing out the contradiction. Yes, I’m aware that is a reductive comparison. It’s for illustrative purposes, not to reduce the plight of trans people to a hobby. Don’t come at me.
I imagine that trip wasn’t quite as carefree as it was meant to be
