Well, since it started out with Zumbo and Imus . . .
The only part of the analogy that's accurate is that they both got fired for something they wrote/said. The big difference is, Zumbo's own "fan base" (gun owners) went after him. His case is more analogous to the Dixie Chicks, whose fans voted with their feet. Wasn't Imus' fans who got him fired.
As someone else mentioned earlier . . . where did Imus pick up that language? From the rappers! Comes out of the blacks' own, self-destructive culture. Heard a black female professor from Vanderbilt comment that it was far more hurtful to her when she hears a black man referring to nappy-headed hos than when it comes from "some jerk like Imus". She's exactly right. Sharpton and Jackson, if they want to do something really worthwhile, ought to be tackling a much tougher target than Imus: gangsta rap, and what that music is doing to the black community. That's what they ought to be pushing to get banned from the airwaves.
