Reverse racism is used (in my experience) to define racist behaviors taken as a response to "original" racism. Examples include quota systems at universities, or otherwise discriminating against whites/majorities in the name of social justice.
It's racism, but with a modifier to make it clear what's being talked about. I don't know why you're trying so hard to make it "not a thing".
