I'm asking specifically about the racists. If we were talking about bad things in general, that would be at or near the top of my list along with climate change.
I'm sure many of the marchers happened to be racist but I'm not sure that can be characterized as the main point or driver of why they were there.
You can definitely make the case that a lot of Trump supporters are driven by reactionary racial attitudes, but it's not quite the same as open racial intimidation with white robes and burning crosses.
You forget the bombings and assassinations of the 60s and 70s. Nowadays even racists don’t like being called racist. The majority of the population at least want to be more accepting of people not like themselves (even though execution of this attitude is still pretty poor). As I say, the derivative is positive.
