The only thing they mean when they say you're racist is that you don't want white people to go extinct. Nothing else. They don't mean you hate or harbor prejudices against non whites and they know as much. They're dishonest amoral people with a deeply racist agenda of genocide and they project their abhorrent qualities onto you knowing that someone as awful as they are deserves to be removed from society. These are people who will violently lash out when you show them a mirror.
