Let's look at what 50 Cent has done throughout his entire rap career:
Destroyed the career of another black man
Constantly beefed with and attacked other black men
Exploited a negative image of the black male to gain fame and success
Said nothing when recordings of his white boss demeaning black women were released
Openly supported and defended George W. Bush
Dated an ugly old white woman and did nothing when she disrespected him on the radio
Attacked a black man who was being criticized for interrupting a white woman
Adored by wiggers worldwide
So considering all that, it's pretty easy for a black person to hate 50 Cent
