Mostly it's just the regulations around sex that are wack. Jesus has great advice around taking care of the poor, the sick, and the refugee, which are given short shrift by the Christian nationalists on the US.
I consider it more of a "stopped clock" situation; I've found myself getting more and more disillusioned with Christians as I get older, but this is one thing I can agree on.
We should distinguish between the moral condemnation of a behavior and the desire to outlaw it. The latter is hardly Christian in any universal sense and seems to be mostly an effect of Protestant puritanism. For example, many saints have argued to tolerate prostitution and other vices for the sake of man's weakness.
