The equivalent for me is “What rights don’t trans people have?” The text seems like a perfectly reasonable question but online, it is very rarely asked in good faith.
In this case, the context is that in almost every case the questioner knows exactly which rights trans people don’t have (the right to healthcare, the right to family life, the right to a private life, the right to protection from discrimination and violence, etc) but doesn’t care.
The NHS won’t treat a broken leg if there’s a ballsack underneath the dress? Anyone – other than perhaps his ex-wife – taken away Gary’s kids because summat? Punching Jack Monroe carries – righteously – the same punishment as punching someone as obviously cis and het as Teresa May. And as for the private life bit we’re all rather hoping for a bit more of it from xes.
