If Beyonce can have an alter ego and other "Artist" how come Nick Cannon can't have a white alter ego name Connor Smallnut?

Because of the hatred embedded in the melting pot of America, a comedian who doesn't have a track record with racism, racist friends or affiliated to any racist organizations, in fact, married to a biracial woman, Mariah Carey; Nick Cannon can't even dress up like a :totally rad out" white boy because it's now called "reverse racism". Meaning instead of the usual, white racist, it's now someone else returning the treatment. This term, Reverse racism, symbolizes someone who is nonwhite but does something oppressive.

Is Nick Cannon "white dude" look racist? He look like that white boy who had everyone fooled talking about his "24" or (Foes how he says it) but infact was a white boy,  mackelmore, rapping on black music/ black beats.

Is this similar to whites putting on black make up portraying black performers, to entertain or blatantly poke fun in times where slavery was legal and the equivalent of a white man and a black one was non-existing?

How come it's OK for Justin Beaver and miley cyrus, mackamore to mimic black artist and/or black culture but to promote an album called, white people party music it would only make sense, wouldn't it for Nick to get into actual character. American Idol always have whites singing "soul music" when we all know who stabilized the rhythm and blue in R&B.

If Beyonce can have an alter ego and other "Artist", How come Nick Cannon can't have a white alter ego name Connor Smallnut?

"Black face" begun in the most racist times when killing and lynching was done in the public on street corners. As early as 2008, Robert Downey Jr, in Tropic Thunder, played the whole role in "Black costume" but he's just "acting" right?

Hypocrites.

The practice was popular during the 19th century, propagating American racist stereotypes such as the "happy-go-lucky darky on the plantation" or the "dandified coon." This so-called art was popular for about 100 years, starting in the states in the 1830's and qickly making its way overseas".. Read more
