Racism is fictitious.

If somebody feels that they're superior to somebody else because they look a certain way or talk a certain way or have a different skin tone or colour, then they've got an internal superiority complex based on nothing but a figment of their own imagination. They're making this stuff up. To call a white person racist because they imagine themselves to be better than or have the moral right to rule over people of another colour, it's just buying into the indoctrination that keeps us all divided in our little groups.
