1. White people as a whole wish to suppress the speech of black people

2. The speech of anybody else who isn't also white is suppressed

It also presumes, instead of knowing something. Do you know any black people in Italy? Have you heard of any of them complaining that they have no "power to respond"?

EDIT: Case in point; I'm not white, (nearly) all my representatives are white, I don't feel like I have no power to respond. Stop making non-whites victims.
