Democrats have mostly successfully painted the entire Republican party as racist. Despite many decades of Democrat establishment racism (racism which I argue didn’t go away but turned into something more insidious). They get around minority Republicans by calling them improper members of that minority. If you are a minority Republican, you must not really be black/female/gay/Hispanic/whatever.
I was getting ready to argue baboons, but linked to “ignorant blacks” that’s a bit rough to push against. There have been several people losing their minds over phrases like “monkey up” and calling people dogs and linking it to racism rather than either being rude or hard knuckle politics.
