After JKR said her shit, I started to outline a post breaking down all the problems with the "transition regret" arguments, but it gave me such a headache--and heartache--that I decided not to go through with it. People like JKR use an enormous number of underhanded, exploitative rhetorical tricks to invalidate trans identities, and fully refuting them all takes a level of time, effort, and emotional labor that most trans people can't realistically invest, while most cis people either don't have the necessary knowledge or (frankly) don't care enough. This can leave people with the impression that these points aren't being refuted because they're impossible to refute, when it's really just that nobody wants to be the one to wade into the garbage dump of disingenuous argumentation, smug paternalism, concern trolling, bigotry, and lies.

All this to say, while I haven't watched the video, kudos to Shonalika for going there. It is not easy or comfortable to stand up and publicly debate your own right to exist--and bigots actually depend on nobody being willing to do it.
