I have no idea who even organized the rally. Have you any first-hand evidence of who was there and what they were doing?
Richard Spencer organized it. I would provide the links, but I’m pretty sure we can’t link to Storm Front.
And yes, they were chanting “Jews won’t replace us” and “Blood and Soil.” (Which is a ridiculous thing for any American to chant. We are a society built on a creed, not attachment to a land).
