Is that really so? Has this been researched over longer periods?

I'm honestly curious, because I'm probably biased when I think about medieval inquisitions or 1930 Race theories. Was, say, a black person in Rome treated bad because of racism? Were Jews hated in ancient early Muslim cities? Were there no same sex couples in, say, a 1500 village at the swedish coast? I can imagine many 'queer' were just accepted as such in many communities throughout the world, throughout the ages. But I can just as well imagine it being literally deadly to be even a little out of line, just as well.
