Now granted the OP is an idiot and made this a Dem vs Repub thing, but you have made this claim multiple times before that Democrats aren't or can't be racist and that's what I'm responding to.
For example, do you even read or listen to black people? They may hate Republicans and vote Democratic 90% of the time, but there are many that will still say the party supports racism. Hell, the President (a Democrat) wrote the two big crime bills of the 80's and 90's that have been called leading examples of systemic racism and the New Jim Crow. So don't tell me they aren't running your party.
In 2021 there are very few (white) people that like to be called racist. It's not really a good look in much of society to be viewed that way. So there's almost an element of power in calling someone else that term. And it's almost a defense mechanism, "If I'm an old white person who votes Democratic and calls others racist then I'm safe and that deflects from my own actions" (see: person who thanked your post as Exhibit A).
Look at all the claims of how rampant racism is at our Universities. Do you think it's a bunch of uneducated unvaxxed trailer park living Trump voting right-wingers who run these institutions? How can these places dominated by liberals foster such an environment if liberals aren't or can't be racist?
You know one reason things won't change? Because Democrats like yourself won't acknowledge you need to.
Edit: It should be said the whole idea of how we define racism is changing (see Kendi, Ibram: How To Be An Anti-Racist as a prime example).
