This is very much the way it was when I was growing up in southern Indiana in the 1950s/60s. A few small, rural communities in a farming county. Culturally it was almost identical to this. Simple minded, family oriented, a place where everyone knew everyone's business (more or less), where there might be suspicions but they were seldom voiced. Such things just weren't talked about.
Take the country prosecuting attorney (male) who was engaged (for years) to a high school English teacher (female). Both were well respected in the community and fairly well known. They chose to hide their sexuality by presenting themselves publicly as a couple but secretly both were gay. The attorney was murdered by a trick but the above-ground story was he was murdered and robbed by a hitch hiker.
Or take the man who ran a small printing company with his wife, his mother, his sister, an adopted son who had been a foster child, and me. It was a very sick situation and I had no idea when I began working there just what was going on. But eventually it became clear to me that the man had been sexually abusing the boy for years and was madly 'in love' with him. The boy (an older teenager by the time I came into this) wasn't gay (so far as I could tell) but was very emotionally manipulated and conflicted. He was also very angry, self abusive (as well as 'other' abusive), acting out his rage. The mother, wife and sister 'knew' what was going on but they were all in denial about it and simply, psychologically and culturally, were ill equipped to know how to deal with it. During the year I worked there, there were several instances where the whole situation threatened to blow up to the point it would become a public scandal. It was a severely dysfunctional family system BUT one the county prosecuting attorney mentioned previously knew about. Years later the man involved in all this would die of HIV although, of course, that was never admitted by the family. I have no idea what became of the boy.
These are just two examples (and there are others) of what the repression of homosexuality does to a society. It literally kills people, destroys families and makes people sick. Then everyone in denial wonders "what went wrong."
