It was a racist rally, sponsored by racists, coordinated by racists, promoted by racists, and filled with racist speakers.Trump was clear that he was not referring to the white supremacists organizers, but to those who showed up, just to support historical statues.
There was no one there on the right but racists.
Trump's words prove that he thought there were. He was certainly explicitly clear that he was not referring to the neo-nazis, but to the people that were not neo-nazis that he (and I ) believe were also there.
I understand if you think we are wrong about that. But lying and claiming we are saying something that we are not saying, is you being a lying asshole.
