It is rather suspicious how fast a lot of straight people were to jump on the TRA train (when you compare it to the more gradual trajectory LGB acceptance had). I think part of it is mindlessly following "woke" social media and wanting to be praised for being on the "right side of history" (as other commentators pointed out). But I suspect a lot of straight people still hold disdain (disgust?) for same sex attracted individuals, yet can't openly express it because it's no longer socially acceptable to be homophobic (at least in western countries).

That's how you get a worryingly large number of parents who would rather transition their GNC children, than accept that said children might grow up to discover they are homosexual or bisexual. For whatever reason, it appears that the more conservative someone's values are, the more they lean towards transitioning as a "cure" for homosexuality, or for fixing behaviors that don't align with specific gender roles. How these people call themselves "progressive" while telling a little boy who's playing with dolls that he might be a girl because of it, is beyond my ability to understand.
