I think it’s pretty simple, I said what I meant. MAGA racist who are people who are racist AND support Trump. Being a Trump supporter doesn’t necessarily make a person racist. What drives some Trump supporters is classism (i.e. wealthy vs not wealthy, the stock markets). Some are driven by divisive politics (them against us — rich vs — poor, South vs North). Some are just loyal to the GOP no matter what (right, middle of the road, wrong — and indifferent). And some people are just plain old racist (Alt Right, KKK, Proud Boys, and many formal institutions). A person can be racist, to some extent we all are (via nature/nurture or environment/living in America).
Many of Trump supporters are indeed racists, and violent. For the purposes of this particular statement, these are the folks I’m referring to.
