I don't think it does any more than any other form of nationalism does. Are the Baltic countries violent in your eyes? Their nationalism necessarily is hard to distinguish from ethnic nationalism, because they're very homogeneous. All they'd need to do to be white nationalists is to declare so openly. They're a pretty peaceful bunch, unless you invade them (like the Soviets found out in the Winter War).
Communism on the other hand, is necessarily violent, it cannot function without violently suppressing those who do not believe in it, and it will, always and without fail, go on an eradication trip to do so.
