This guy is probably one of two types: a) He’s a culture warrior who gets a little thrill if he makes life a bit harder for the gays because he was told they are the enemy or b) he needs to uphold his current cultural zeitgeist because if people are allowed to do the things that make them happy then what’s stopping him from banging his hot neighbor Greg and if he can do that he’s wasted his life married to a person he’s not actually attracted to and it was all a lie. So he goes super hard on being anti-gay to stop those intrusive thoughts. Stay occupied. Don’t think about it. Hate hate hate.
