I've never heard your definition of racism ("attributes that can be factually proven"?). In my experience, racism is subjective and every rationalization is done afterwards. How often have you heard of someone convincing an avowed racist of anything based on arguments?
"I've always thought <class of people> were dumb, weak, morally bankrupt, and have brought decadence to our country, but now that I look at this scientific study I'm convinced otherwise".
