This is a political bubble view if I've ever seen one. Evangelical Christians (those that are practicing and going to church regularly and very zealous in their beliefs) make up a tiny minority of those currently aligning with the right, and many are fervent never Trump'ers and prefer a Romney or Bush type Republican. They've simply lost their voice within the party. Most "conservatives" are okay with gay marriage and abortion up to a 22-24 week term (about the point where the fetus can experience pain). Devout religious practice by every survey and measure has fallen into the minority in the US and the country is largely agnostic at best if not in profession, then in practice. They don't care about the
The middle finger is by a larger portion of the working blue collar middle class that has had their economic base wiped out by free trade or trade policies like negative tariff's (ex: China subsidizes shipping of products to the US, hiding the true costs and incentivizing higher carbon/energy consumption practices like shipping raw products overseas to be processed and shipped back, its why you can ship something from Shenzhen for 30 cents when it costs $50-$80 to send the same small item the other way). The few manufacturing facilities and industries here view this as a hostile predatory business practice, similar to when Walmart or chain moves in, cuts prices to cost/loss, drives local competition out of business, then raises prices after they're gone to at or above what the prior businesses sold at. You'll never see this reported on because its a practice that benefits the very rich and people in cities who like cheap goods and don't care where it came from. They view this trade war as a return shots to a war or attacks that's been ongoing for 20 years.
If you frame this as anything outside of working class politics or rural vs metropolitan you're still viewing politics from a view point of 30 years ago. People in rural or less populated areas don't care if people in NYC pay more for goods. They've had their entire economic infrastructure ripped out from under them and were told to learn to code or move to an expensive city or something after they're already barely surviving. They've seen the cost of living raise as they're outcompeted in lower cost housing segments by an influx of migrants who need housing and buy up/rent out the few affordable lower cost areas of a city or location to live. Meanwhile everyone living in the nice neighborhoods thinks its all racism and enjoys the novel new ethnic restaurants popping up. They're experiencing none of the downsides and all of the upsides so find it easy to say its entirely xenophobia. People not affected by it at the same levels in academic or corporate jobs are able to talk in idealist terms about how great these things are because they don't have to deal with the base realities of the issue or fentanyl epidemic, etc. So yes, that segment of the population is very much in a mood of "if we have to suffer, you'll suffer too until you start giving a shit about us instead of entirely what just benefits you". Whether or not this is entirely correct or nuanced doesn't matter. That's the overwhelming sentiment. If you still keep thinking of politics from the viewpoint of what's discussed in bars and dinner tables in cities with a population >500k or everyone in your friend group has a 4 year degree and gets their politics from major outlets, you're dealing with outdated information and context. Even highly educated conservative pundits who live in high population density areas don't get it and have struggled to catch up with the huge shift over the last 10 years.
