Come on, you know it won't.
What transpeople did was organizing themselves in groups, and going to knock on the State's door to ask for money, treatments, and laws allowing them to do whatever troons do. Hitching themselves to the gays and the feminists was also a way to buff their numbers. They met little resistance besides some radfems, and religious groups.
Transracialists can't do that. First, there's very few of them, not enough to associate, second, they would experience a huge, violent pushback from minorities who have already organized themselves to present a unified front like... all racial minorities.
Right now no-one support transracialism. The only people doing it are turbo-conservative, they are pretending to piss-off the Left in general and the troons in particular.
