I am not sure what is the scariest part of the White Nationalists/KKK/Nazi march in Charlottesville. But to me, it was their brazen attitude of being unmasked to the world as racists. There was no attempt to cover faces and identities. In the age of social media, these racist march participants knew that their faces would be plastered all over the internet, and yet they marched anyway.
So, it is incumbent on all of us to name these violence-inciting racists, call them out, and publicly scorn them as unacceptable.
See a Nazi? Call them a Nazi.
