I would dismiss it out of hand by simple virtue of claiming that Nick Fuentes and Enrique Tarrio are "white-nationalists and neo-fascists." These are the completely unsupported and typical Leftist smears against thorns in their side. Their usage is meaningless, and a note including them is as trustworthy as a $20 in Minneapolis.

As for the Stormer targeting Spanish-speakers, there are plenty of randos you could use simply as foot soldiers for your ideology, and "white supremacists" are regularly fighting people that also target Spanish-speakers, anyway. Why not reach out to them to make them Allies of convenience?

The fact of the matter is that the meaning of "white supremacist" is diluted into meaninglessness when you start to ascribe it to people that are NOT WHITE. Hispanics can have light skin, but they're still not white. Their inclusion into the label of "white," I strongly suspect, is to merge a clearly Hispanic crime percentage into actual white people's much smaller one in order to falsify statistics for political purposes.
