I believe if you went through a tape of virtually any large public meeting of African American (like Tavis Smiley's yearly state of the black nation conference C-Span covers every year, NAACP, Obama’s Church, etc. and transcribed every remark critical of whites, “white America”, the “white man” which received audience applause, select the most hostile and radical of those remarks
and then
assembled a large randomly selected audience of whites (Americans whose ancestors were of European Caucasians origin) and had speakers repeat the above transcribed more radical remarks with ‘black’ or ‘African American’ substituted for white that those remarks would be greeted with boos not applause and that white audience members would stand up and verbally attack the speakers, shout them down and if that was not successful walk out.
It is a simple fact of American life that a black audience will not just tolerate but applaud anti-white hate speech and a white audience will react very negatively to anti-black hate speech.
