Not saying that it's necessarily what's going on there, but there's a certain subset of insane white supremacist conspiracy theories that thinks that Christianity is a Jewish conspiracy to make their beliefs more palatable to the masses and spread their influence or something along those lines. It'spart of the reason some white supremacists are into norse paganism and such. You'll also get bullshit about the "wrong" branches of Christianity being controlled by the Jews, etc.

It's all completely insane of course, but I guess there's something that almost approaches logic to it, it's kind of weird for people who are so proud of being white to follow the teachings of a middle eastern religion.

There's a pretty interesting rabbit hole to go down with the various factions of white supremacist assholes, while they're all pretty much the same in all the ways that matter to any of us who aren't pieces of shit, under the surface there's actually a lot of different little philosophical differences, and for a long time they really struggled to put together a united movement.
