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.
The only actual country in East Asia where gay marriage is legal is Nepal. Outside of that, it is only legal on Taiwan (unless your gay spouse is mainland Chinese, marrying anybody from the PRC has recently become illegal there). This is all in spite of East Asian countries as different as Japan, Vietnam or Thailand having higher public support for gay marriage than the US - this support does not extend to legal recognition, but instead attempts of reform have remained stuck in a judicial and buerocratic limbo for years in all three of these places.
