Nobody has provided a definition...more anecdotal references than anything.
I think the entire racism conversation in this country is inefficient at best as a result of not having a working definition. The lack of definition actually compounds the problem.
How about just the actual definition?
Racism
noun
prejudice, discrimination, or antagonism directed against someone of a different race based on the belief that one's own race is superior.

It's not more complicated than that unless you are intentionally trying to make it more complicated
