There are lots of things in every cultures religious texts that don't reflect the current state of the religion. Things that people used to believe, but don't believe anymore. When white supremacists stop believing in white supremacy, then they won't get (as much)shit for ethnocentrism. It'll still be there as a part of their history and a nasty thorn in their establishment myths, ofc. Unlike jews, however, we'll have to come up with another word for white supremacists who no longer believe in white supremacy - normal..sane, maybe?
