There has been a small subset of liberals who view all conservatives as racists and bigots, and the GOP as nearly synonymous with the KKK. I've see it in blog posts on this and liberal media sites, with no concern by moderators on those with moderation. 

Since Charlottesville this view is becoming more mainstream, as we see media and liberal groups demanding statements of condemnation of white supremacists from every conservative and Republican they can find, with the implication you are probably "one of them" if you didn't rush out to do so immediately after Charlottesville, even towards those who personally have no hint of bigotry in their background.  Kind of a "loyalty oath" to prove you don't wear a white hood in your spare time. 

I think demanding such proclamations of people whose only "crime" is to hold conservative views or identify as GOP to be as alarming and repugnant as if every Democrat had to state for the record they are not a member of the Communist party.
