What’s your definition of racism? White supremacists are certainly racist and would probably tell you that they are racist, too. That’s their whole message. Nazi Germany Leaders would probably have been ok with having been called racist, too. They were talking about being superior than other races all the time.
For me, it depends upon how the 'groups' part is applied.
An example that seems sexist: women love shoes.
However, this isn't sexist... it's simply statistically true. Where *isms come into play, where sexism occurs, is seeing the individual and then thinking "Ah, a woman... clearly she must love shoes".
Applying group derived statistical fact to individuals is where racism, sexism occurs.
Another example, black people in America show lower outcomes on IQ tests. There is a lot of debate as to why, whether it is genetic (an example, do Black people have less incidents of autism? Autism is often correlated with mental issues, but also conversely with higher test scores in some areas.) But really, it doesn't matter why. Whether it is genetic, whether it is cultural, or what.
What matters is that we understand the group statistic exists, but that no matter what we do not simply apply such thought processes to the individual. After all, a few percentage in group testing has no basis for determining if the person in front of me is capable or not.
I've met (as an example) some very unintelligent white people, and some very intelligent black people, a few percentage difference as a group is not relevant here.
Yet if we pretend group differences don't exist, how can we possible try to fix it.. if it is cultural? Or worse, what if it is environmental, such as... poor nutrition which hurts brain development during youth? Such things can be fixed, yet if we pretend there is no difference, how can we try to fix it?
So again, the primary must be to treat individuals as just that, and treat groups as just that, otherwise.. how are we being fair?
