It varies. I often write stories about queer teenagers persecuted by conservative Christians. I wrote a story last week about a 17-year-old who was literally kidnapped from his own bedroom in the middle of the night and sent to a camp in the Dominican Republic run by conservative American Christians. (Mostly ordinary Baptists.)
They literally beat and tortured him. (I am not exaggerating even a little.) They held him in solitary confinement. After he turned 18, some of his friends friends had to convince a federal magistrate to issue a writ of habeas corpus to get him freed from the camp.
What did those Christians want? They wanted him to "accept Jesus" so he would no longer be gay. He was already a Christian, though. The people who ran the camp were convinced he couldn't actually have "accepted Jesus." They were convinced that if he had "accepted Jesus," Jesus would have taken away his same-sex sexual attractions.
It's hard to understate how intentionally ignorant and superstitious these people are. They don't care about facts and reality. I can't wrap my mind around that, but there you have it.
Also, they evidently don't care much about their own sacred texts, at least not the actual teachings of Jesus, who (color me crazy) would likely have disapproved of torturing teenagers.
That's one end of the spectrum. Delusional, superstitious Christians believe that Jesus will turn gay people straight (or cis) if they ask Jesus sincerely enough. The fact that mountains of evidence demonstrate to the contrary is evidently of no nevermind to them. (Because delusion and superstition don't care about evidence.)
The other side of the spectrum for homophobic conservative Christians is an expectation (a demand, actually) that gay and trans people live as cis/straight people, despite however we might actually be wired.
This group is willing to admit that we can't stop being gay, but they insist that we live either without love and romance, or that we marry a partner we aren't attracted to. They apparently have no problem demanding that we live unfulfilled lives.
They insist that trans people live with dysphoria and live conventional cis-acting lives, whatever the consequences.
Look, the current Speaker of the House, Mike Johnson, is on the record saying that he wants same-sex sex to be against the law.
He's a fundamentalist Christian. That's what fundamentalist Christians want.
Because, apparently, Jesus taught them to be assholes.
I can't find that teaching anywhere in the New Testament, but there you have it.
