My take is that it's eventually going to become "uncool" as both the rabid proponents and victims of the ideology age out. I can also see it continuing to take hits as more people challenge the obviously unhinged rhetoric and ethically unsound "affirmative care model" of fast tracking children into genital mutilation. We're already seeing a lot of teens speak out about their deep regrets and there will only be more in the coming years.

It will always be around in one form or another because 1) there will always be men f'd in the head enough to scream about their fetish being publicly acceptable, 2) it's too good of a shield for pedos and sexual predators for them to totally give up on it, and 3) there are some very very rich people providing funding to constantly shove it down our throats. The last is part of the reason I think it hasn't faded as some of the other trends you've mentioned.

I also see non-binary and the social trend of transness to be this generation's emo or goth, and those had several good years in them before their wide popularity fizzled. Likewise, there are still emos and goths but in much smaller numbers, i.e. I had my pick of 3-4 goth clubs pretty much every weekend in the 90s and now, with rare exceptions, the scene has been reduced to monthly events.
