When they call someone racist today… it is precisely because he is not a racist. They are projecting their own racism.
Ditto, when your mother calls me a child abuser… it is precisely because I am advocate of non-violence and non-child abuse. She is diverting attention of who the real child abuser is, herself. Exact same pattern.
In Sneeches, Dr Seuss describes how not to be racist. And for that his books must be burned, because they want kids to grow knowing their skin color does not matter.
