I often see in (non-academic, progressive cirlces) a general claim that the ancient world was more accepting of LGBT people. By 'more accepting', I mean more tolerant than the dominant mainstream which was the reason homosexual intercourse was outlawed for a time (In Israel it was outlawed until around the 90's, if I remember correctly). By 'ancient', I mean either pre-industrial or pre-Christian civilization. Since these aren't academic discussions, these terms can change meanings depending on contexts.

Of course, I'm aware my question doesn't have a black-n-white answer, so feel free to elaborate or modify it!
