> But this is the case on everything though, literally almost everyone used to be anti or neutral about LGBT 20 years ago, and now is supportive
If by “literally almost everyone” you mean “a majority, but not a particularly overwhelmingly large majority”, sure. Both opposed 20 years ago and supportive now:
2001-2019 support for gay marriage in Pew polling went from 57-35 against to 61-31 in favor. Did everyone change their mind? No, about 1 in 4 did.
Possibly far fewer, since it's not the same population, and those aging into polling were much more accepting (on average) than those, um, "aging out."
