>It isn't normal behavior in humans, it shows that something went way off the rails.
This is literally not an argument against homosexuality. You already believe that homosexuality is something bad and "unnatural" and you conclude that "something went way off the rails". Homosexuality being degenerative is not a fact but merely your own (wrong) opinion.
>Likely, overpopulation and other cultural trends are making life incompatible with society's natural behavior.
Homosexuality is not a nature's population control tool simply because it clearly does not work. Modern cultural trends are responsible for more people being open about their preferences, but they don't make more gays. You are born either straight or gay.
Your whole argument about cultural revolution does not work either for several reasons:
1. Your claim that there were no gays in paleolithic societies is sourced from your ass
2. Greeks had strong morriage institution and no harem culture, yet homosexuality used to be accepted/not persecuted
3. Once again, how do you exactly know what sexual behavior humans "originaly" had. There are plenty of wild animals that are gay, why would't gay paleolithic people exist?
To clarify, I don't find trannies totally normal. I just tolerate them because I believe people have the right to do whatever they want as long as they don't bother me.
Traditional institutions are falling apart not because they were deeply flawed, but because they don't work as effectively as modern institutions.
No one was cheering or dismantling anything on purpose. Thing are just dying off because we don't need them anymore. To be specific, the main traditional function of the family institution is to raise children, but family is not needed for that anymore. Labor efficiency has increased, thanks to technological progress, which makes it easier for one parent to provide for his/her children.
