No. People of color cannot be racist. Racism is prejudice plus power. Do not give me a dictionary definition of racism. There are multiple problems with this. Who do you think writes dictionaries, for one? Two, if you ever would use a dictionary to look up a concept (and not say, an encyclopedia or any legitimate source on the internet), you’ve got bigger problems than a misunderstanding of racism. Three, dictionary definitions tend to come about after a term is used in a certain way, not before. The way the word is used can define how it is defined in the dictionary. The definition of racism comes from 1908, so I don’t understand how you would think it is a good idea to use it.
