The problem is that he suggested that Republicans have a monopoly and own the patent on racism. There is a sunshine-free zone where he is welcome to shove his insults and stupid ideas.He didn’t revise history. He did nit say that Republicans started the KKK. It sounds like he’s talking about now. That’s not historical revision.
He’s either correct about now or not. I think at this point it’s on you to prove him wrong. List the current Democrats who are KKK members.
