I'm more exposed to American conservatism. And even here I barely understand it. I used to be Christian, but I left the religion before I realized I was bi, and before I knew genderfluidity and trans people existed.
I guess I'd have to know why individual religious groups, countries, cities,(etc...) have anti-LGBTQ beliefs. Maybe there are no blanket statements that properly address it for the entire world.
For superpowers and countries that have regional conflicts (usually cold conflicts), the idea is that women are weak, gay men are effeminate thus they would be weak soldiers. For whatever reason, their military is based and strong and can turn any limp wrist teenager into a special forces killer, but they can’t turn a supposedly weak, gay man into a basic soldier lol. Says more about the military than homosexuality.
