This is a man casting a gay sex demon out of another man. I mean not really, mostly because as everyone has pointed out, no gay demon would show up to church in that vest.
Of course it’s super-upsetting to see someone convinced that their sexuality is caused by a demon, so convinced that they find themselves pretending to be the demon. So let’s keep trying to not do that! And meanwhile laugh at the asshole preachers who pretend to cast out demons.
