Words have meaning.
Many words, including this one, have multiple meanings. A lot of people define "racism" as racial prejudice. You define it as requiring claimed superiority. Again, its semantics, so I'm not terribly concerned about it.
Defending things that are harmful is indeed a bad thing. But it would seem bad to also inject false motives of people, just to make it a race issue.
Discrimination based on race is a race issue. Isn't it? What are you saying here?
