Hate for gay people used to be the one common denominator from pretty much every religion. Times have changed for the better. Today, many of those opposing to same sex unions for religious reasons (there are others who do for other reasons) try to change the narrative and make it about something that it's not. They are the ones who always start talking about sex, sex with animals, pedophilia and all other disgusting behavior, when the issue is about the benefits, entitlements and protections that the law provides when people get married.
The worst part of it are LGBT+ JWs who get convinced of all the hateful crap and go on preaching and endorsing hate for their own selves. Sad (been there myself, though). Some make it out of that nonsense, but not all.
