Painting with a very broad brush.
Utterly ignorant and off base.
I herby declare a fatwa against Southern Baptists, especially those who dance.
Their is no room for their hatred, and dancing.
That was exactly my impression. It seems to me they are relying on the words of the left wing media to characterize this movement called the "Alt-Right."
I've read some commentary written on some sites that consider themselves part of the alt-right (Zman Blog and Vox Day) and they don't seem to be obsessed with race. Their commentary seems to span the gamut of topics, just as with any other conservative discussion website.
If they are racists, It isn't showing up very well in their writings.
