How is calling this racism a dilution of the word. The name clearly suggests that it is treating black people differently from non-black people. The fact that the word "racism" has been stigmatized to the point where an activity must be both racist-proper and harmful to a recognized marginalized group is irrelevant. We can argue about wheather or not the racism in this group is significant or even negative, but that is irrelevant to the fact that, at least the name, is racist.
