Correct, I think it is important to acknowledge the President of the United States is racist. I think it leads to policies like the one that unnecessarily separated thousands of innocent children from their parents, which the entire country had to force Trump to reverse. I think it leads to him directing violent state suppression of First Amendment rights like we saw at Lafayette Square. I think it exacerbates hundreds of protests against police brutality and encourages violence on both sides instead of encouraging healing and solutions. It leads to him hanging on to people like Stephen Miller as a top advisor with a lot of influence, even though Stephen Miller is a demonstrated racist, even though Trump has fired many other advisors. It leads to Trump looking the other way at violent white nationalists but eager to escalate things by using federal troops against Americans and unmarked federal agents scooping up Americans on the streets of Portland, until he was stopped. His own General Mattis stopped short of calling Trump racist, but agrees with the chain of causation wherein the division he sows makes Trump a danger to our Constitution.
Maybe you think I call people racist for fun. I assure you I do not. I feel Trump's racism has dangerous consequences and as an American - and perhaps especially, as a white man - I have a moral obligation to call him out and condemn it.
If you think it is a game and don't like it, then don't play. I said Trump is racist. You replied "so is Biden". That response was absurd, so now you want to take your ball and go home. Which is probably a good decision.
