You have an exceptionally poor understanding of purity spiraling, and the history of NWTI, specifically how Covington got there in the first place, if you think it amounts to “rejecting race mixers and homosexuals”. Nearly the full sum of humanity rejected homosexuals and degrees of interethnic mixing for all of its history, but it did not suffer from what we call purity spiraling.

The article goes through some pain defining what purity spiraling is as a social mechanic, where it arises, and what it isn't. It also describes how it plays into other problems that commonly plague far-right groups seeking coalescence.

I suggest actually reading the article before writing a takedown as dim-witted as this.
