This, from another article I just wrote today:

As my (brilliant Black PhD) buddy Rosennab said the other day with her typical focused observational skills, you don’t have permission to spray your grafitti over someone else’s work.

But too many white guys (witness the debates) feel it's okay to spray their graffiti, sperm, spew their hatred and ugliness ALL OVER EVERYONE's work.

Not all, witness good guys commenting here. But plenty, witness White Clueless commenting here.
