So, as far as I'm aware, there is "racism-as-defined-in-some-academic-circles", where it's only racism when it's systematic and directed by a privileged ethnic group against an unprivileged ethnic group. Which is (IMHO) different from what non-academic people understand racism. Maybe that's what parent means?

Honest question: does it have to be directed by "a privileged ethnic group" or is it valid if it is by any general group or even a single, privileged person?
Presumably, the "privileged group" should have a perceived ethnic composition different from that of the "unprivileged group", otherwise discrimination can't be based on ethnicity. But I guess it doesn't mean that all members of that ethnic group need to share this outlook.
That said, I'm no academic, but I remember reading something about this a few years ago, in the case of a woman in France accused of anti-white racism.
You shouldn't be generalizing on race if you want me to believe that.
