>Your entire argument hinges upon the need to force same-sex attracted people back into the closet, that's insane and you're insane for arguing that we should do that

They're not arguing that. They're saying that the increasing visibility of and conceptualization of homosexuality meant that men felt the need to signal that they were not homosexual. That isn't saying that we should go back, it's just saying what likely happened. Even today you can see greater male physical affection in places where homosexuality is extremely taboo like in Saudi Arabia, where it's not rare for male friends to hold hands.

The solution to this is not that gay people should go back in the closet, it's that there should be a reduction in the stigma associated with being gay (though even without a stigma, most people don't want to be perceived as a sexuality they're not, so this might not work). Identifying why things likely shook out in a certain way is not an attack on the gay community.
