I was alive in the 80s and 90s and from my memory talking to a large number of adults from all walks of life basically everyone was what you’d call homophobic or hateful, the really out there radical left wing whacko position was leave them alone they aren’t hurting anyone, which was a rare position. Most believed it was vaguely wrong. If you ran in radical gay activist circles in NYC maybe things were different, certainly wasn’t in the mainstream. Most people were not frothing maniacs, just slightly negative.
I think part of the problem is that to the lay person who wasn’t there they use media to form their opinions on the past, and take the comparative lack of mention of it to say hey it didn’t really exist. Thing was media tended to shy away from the issue, hell Star Trek refused to produce a gay plot line in the late eighties.
I don’t know why I find this of import, but to find someone even close to a modern conception of someone not homophobic you’d have probably had to interview a couple hundred people.
