Well under that standard, you can justify anything.
Every report from Friday night - from the right and from the left - mentions the “Jews Won’t Replace Us” and “Blood and Soil” chants. I suppose everyone could be lying.
So, let’s change the question, if you went to this rally thinking you were going to honor good ol Bobby Lee, and ran into a lot of dudes chanting about Jews and giving Nazi salutes, what would you do?
I would assume that I somehow found my way into a Democrat Party rally, and take a hike. :-)
