"Socially conservative" just means bigoted, doesn't it? We can just say they're bigots, right? Unless there's a counter-example I've missed.
If someone wants to keep to their own values, they can already do that.
But the very project of insisting *society* not change too much is inherently about telling other people what they mustn't accept and what they can't change, from a position of ignorance (you don't have the information a million other people have about their own lives).
So, bigots.
