The only time I recall any rapper being criticized for the violent reprehensible lyrics in rap, was when “M & M” was criticized one year at some music awards show. I think he was up for an award, and some criticized the genre of rap music and Eminem particulary.
But, what was striking was that Eminem is white, in a field in which almost all of the “performers” are black. I think it’s politically incorrect to criticize a black rapper. But it’s okay to criticize rap if you pick on Eminem.
So Michelle Obama is just daring anybody to say anything, knowing that any criticism will be deflected as racism.
he also was crucified by the gay lobby for the use of the word “faggot” in a song. He ended up performing with Elton John to satisfy the likes of Rachel Maddow and the LBGT community that he was not afraid of homosexuals (homophobe)
