What’s with this “reverse racism” BS?

I always see people use it when someone’s calling them out for being racist against white people. “Reverse racism” isn’t even a thing! White people are human too and can experience racism like anyone else. If you disagree, then you’re a racist and like all racists, you’re only denying it to avoid acknowledging you’re a garbage human being. If you speak out against white people who are racist against people of color and then defend people of color being racist against white people with that “reverse racism” crap, you’re just being hypocritical. Anyone and everyone can experience racism and all racism is bad. Or none of it is! Pick one.
