This postscript, from Rod Dreher (who is both anti-gay and pro-evangelical), is anecdotal but interesting:
I just returned from a lunch meeting with a group of conservative Evangelicals, including a few pastors. […] A couple of people in college ministry were at the table. They said that it is impossible to overstate how alienating the enthusiastic support their parents gave to Donald Trump was to their students. A number of college students have left the church entirely over it.
“How is that possible?” I asked one of the campus ministers. “How do you decide to leave Christianity altogether over who your parents voted for? That makes no sense to me.”
He said that in Evangelical circles, it’s common for college students to be skeptical at best of their parents’ theological views. For a lot of them, their parents’ backing of Donald Trump made everything they had been taught as kids about Christianity a lie. Their parents were the primary face of Evangelical Christianity to them, and to see this happen was shattering. They concluded that Christianity must be all about the economy, or tribalism, and so forth. One pastor said that a young man he ministers to in college posted a criticism of Trump on Facebook, and was cut off financially by his parents because of it.
Listening to these pastors and laypeople talking about the Trump effect on younger Christians was quite sobering to me. An older pastor said that it is impossible to separate the Nashville Statement1 from the massive support white Evangelicals gave to Trump. Impossible to separate, I mean, in the mind of the young.
“But Russell Moore signed it, and other Trump critics among Evangelicals,” I said.
“I know, and I’ve tried to tell people that,” said this pastor, a conservative Evangelical. “It doesn’t matter to them. All they see is a bunch of leaders of a movement who voted for a sexually corrupt man like Donald Trump are now trying to take a public stand on sexual morality for gays. It’s totally hypocritical to them.
Young evangelicals are simply more pro-gay than their parents – although less pro-gay than other young people. I haven’t seen any survey contrasting young evangelicals’ attitude about transsexuality to that of their parents, but it wouldn’t surprise me if that’s trending in a similar direction (although probably not as advanced yet).
