I don’t get it either. I imagine it’s a side effect of being naturally more fearful, and stupid, so they get sucked into the right-wing media spiral which then tells them this is one more thing for them to be afraid of. Maybe. I think the reason can just be loosely tied to “family values”, or religion, or “our country”, or drag queens, etc. and that’s all it takes. They don’t need a solid line of logic and reason, they just need to be led to the conclusion along any path, then anger and fear cements the response in place.
