Well it is obviously uncool to hate on anyone based on their sexual orientation.
Personally, I think that no one chooses to be gay. Thats just how some people are programmed. For straight people its very easy to think that its gross and unnatural but for someone whos gay, they only feel attracted to same sex people. Gays have been around since humans have been. So many ancient Greek, Japanese, Chinese mythology talk about gay love and gay relationships so its certainly not a new “western plague” as many people call it.
