These imbeciles really think that if a race war broke out, it'd be them and all the whites against the non-whites, instead of it being them against everyone else.
Free speech is nice n'all, but Nazi marches should not be tolerated. If your ideology is anything remotely like this, you should not be protected, just as someone yelling "fire!" in a crowded theatre, or someone sending death threats, is not protected. They are avowed racists, bigots towards just about everyone, and seek to build a Nazi-USA. Fuck free speech if this is the upshot of it.
