At some point in history, a lot of extremely bad opinions went from “almost everyone” to “vast majority” to an ever shrinking minority. Just to name a few:
- black people are inferior - women are inferior - gay people shouldn’t be allowed to marry - Native Americans are savages - Depression/anxiety should be stigmatized
Each of these opinions followed a predictable but long path where more exposure to better opinions eventually won out. I’m unaware of any progressive opinion on egalitarianism that has failed to become mainstream given a long enough time horizon.
I don’t see any reason why this current “debate” will turn out any differently.
