1. He could honor people doing racial justice work - Does not doing this make someone a racist? Silly. Also, here is a direct quote from February 2020 (see how I use actual evidence) "We’re here with some of the black leaders of our country and — people that are highly respected and people that have done a fantastic job and, for the most part, have been working on this whole situation with me right from the beginning." Does that sound like something a racist would say?
2. He could stop stoking fear of immigrants - This is not a specific example.
3. He could insist on full investigations of police violence toward black people - This isn't the responsibility of the president. If he got involved in police business people would say he is overreaching. This is again a subjective thing you "feel" he could do. The agencies that are supposed to be involved are.
I try to stick with concrete facts to base my opinions on. This has been a great example where you really want to think he's racist because of what you see in the media but have so far provided 0 objective evidence for your claim.
