What are your thoughts when it comes to 'white supermacy'?

I think there are already too many people who are willfully stupid, so white supremacists just add one more kind to the mix. And I have to scratch my head at how this weekend there's an avowwed white supremacist march in Charlottesville, Va, a town that largely survives on it's large college (UVA). So these proudly moronic people are going to gather by a center of learning hoping to spread the message of how much better stupidity is.
