The thing is that Abrahamic religions were extremely ass backwards on this issue for the longest time. My expectation would be that countries with a majority of atheists or buddhists would never have been as ass backwards about gays in the first place.

IIRC China is supposedly atheist, and so was the Soviet Union, but things were not particularly rosy there either. https://en.wikipedia.org/wiki/LGBT_history_in_the_Soviet_Union
Whether religion or not, it’s often a case of despicable hardliners taking charge and making things worse for pretty much everyone but them.
