My guy, there are entire countries controlled by Islamic Extremists where you're lucky if all they do is kill you when they find out you're LGBT, and it's entirely for "theological reasons."
I put this in quotes, because I'm not nor have I ever been a Muslim. But Islamic Extremists will kill gay people for supposed "theological reasons."
It's most definitely not just America doing it because "mah holy book says it's wrong."
Like I said I am in America and all we see is how backwards other countries are on the topic. It just feels like America is now in the process of becoming one of them
