There is actually quite a bit of difference between the statements "America is a racist country" and "institutional racism exists" or even "there exists a belief of white supremacy."

And even between "America isn't a racist country" and "the people who talk about implicit biases are the real racists," which is closer to what he actually said (allegedly).

(And if we want to have this discussion, I bet we could do it in a way that wasn't "painful and divisive," because I have no desire to be those things, so I'm not going to predict/threaten it.)
