Words have meanings. Racism has nothing to do with power, with or without the quote.
You’re arguing with a dictionary.
I never expect any non-white person to understand that dictionaries contain meanings of words, as this is coming from the POV of a white man; our realities are vastly different in nature and circumstance. This doesn’t mean you can’t understand, but my expectation is not there for you.
P.S. My country denied citizenship for me due to my ethnicity.
