> When she says "black people can't be racist towards white people" she is saying "the oppressed cannot, themselves, oppress their oppressors". That's why they're called "the oppressed".

Then why didn't she just say it like that?

Because that re-definition is always used to attempt to silence or de-rail whoever points out that racism is not exclusive to the white race.

The word racism is already clearly defined. There is no need to enhance it, or re-target it. Use another word, or just state the concept/idea you have.

And on your logic -

Can women be sexist towards men? By your train-of-thought, since men have had that power traditionally, then absolutly the answer is - no. Which is absurd.
