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.
There are a lot of patriarchies out there. I've frequently felt colonization in the US involved cult rules for a breeding program. Anything outside procreation would likely be against the program. Including mastubation because you're not using your libido for making babies. What you're saying could be a blanket statement across a great many colonizing projects.
