I don't think trends and fashion are that aware of their own transience. For example, the rise of Christianity in a region hardly coincides with the rise of other forms of theism. But why not? If people are willing to believe in one imaginary superbeing, why not others whose logic is precisely the same as Christianity? Yet precisely the opposite happens - the one arbitrary belief is forced to delegitimize similar trends, in order to establish itself as not-just-another-arbitrary-theism.
Transgender people have only very recently been given the faintest legitimacy, and they naturally want to defend that against transracialists and otherkin and other movements that basically look like a parody of trans people. Even if their logic isn't fundamentally stronger than those other movements, transgender people have something that actually matters: a little bit of power.
Why should anyone sacrifice that to the altar of logic?
