Never much liked TC and haven't seen clips but I didn't know he was attacking BLM. At least on a racial basis.
I had a rough impression that he defended existing ways and institutions (eg the police) rather than attacking black people, except insofar as he felt they undermined those ways and institutions.
I could be wrong, as i rarely watch him. But i didn't have the impression he was a simple white supremacist. I don't doubt many Trump Republicans are. But i suspect many of them are scared of a multicoloured America.
