A day after having sullied Seinfeld vet Michael Richards on his syndicated radio program, the Rev. Jesse Jackson and other African-American leaders called on the entertainment industry - rappers included - to cease using the racial slur repeatedly uttered during Richards' on-stage tirade.

(The N, however, is, so keep on with your sapphic selves, Ashley and Spencer!)
