> “Antiracist” doesn’t mean “not racist”;

This is true, antiracism is active in the presence of racism, “not racist” may or may not be.

> it’s a Marxist ideology

No, it's not. I suppose if you met “Marxist” metaphorically in that, like Marxism, it posits the existence of a status quo struggle, and calls for consciousness of that struggle and activity within it rather than indifference to it or denial of it, it would be accurate, but that's kind of a weak basis for such an emotionally-loaded metaphor.

> purposeful systemic racism to “balance” the power between racial tribes.

Antiracism does not call for “purposeful systemic racism” for any purpose.
