The proud boys leaders name is Enrique Tario, he's afro-hispanic I believe. Regardless, the proud boys appear to be a multiracial group of Western chauvinists, believing that Western ideas and culture are superior. Progressives seem to believe that Western = white, and that is how they make the leap to white supremacy in this context. Whether Western is about ideas vs skin color isn't a debate I'm interested in, just wanted to provide context.
