I realize your piece is somewhat meant in jest, but I think you've thrown out some real red meat too. To me, there's a reason why Evangelical Christians tend to be pretty nasty when it comes to people who aren't like them.

For example, how could a good Christian following the teachings of Jesus be opposed to immigration? How could a good Christian support stopping desperate refugees from access to succor and support? How could a good Christian support throwing up barbed wire barriers that are certain to kill some of those refugees?

After all, Jesus's teachings are directly contradictory to harming people like that.

I propose that the disconnect is baked into conservative Christianity, as you describe it.

The conservative Christians who support policies that harm people contrary to Jesus's teachings aren't afraid that they'll suffer any consequences. Practicing Jesus's teachings is secondary to them at best.

What they really care about is avoiding hell by having faith that Jesus died for their sins, with the understanding that no level of sinfulness will remove them from the possibility of salvation.

So why should they be loving, kind, inclusive, etc? As far as they are concerned, they don't have to be. They're already "saved," and their prime responsibility is leading others to "salvation."

Note that there's nothing in that system of belief that makes kindness and decency particularly valuable. (Except, perhaps, for the purpose of trying to find converts.)

I think conservative Christianity produces unkind people because of how the religion works. I think conservatives Christians are inevitably unkind and judgemental.
