That's a lot of nonsense and semantic quibbling. Words mean what they are understood to mean. The school of thought she adheres to is attempting to re-define a word, and they have thus far failed. Therefore, no, she cannot expect her audience to adhere to her particular definition of racism since it is highly non-standard outside of certain limited circles. For what it's worth, I also happen to think her "definition" of racism is rubbish. It makes all kinds of assumptions about power dynamics in a given situation and injects motivations into actors where none are known.
