Why hasn't Bill Orielly asked for a boycott of Chrysler?

Why hasn't Bill O'rielly asked for a boycott of Chrysler or Brisk? He asked the American people to boycott Pepsi over Ludacris being on an advertisement. But for some reason he hasn't asked for a boycott of Chrysler or Brisk over Eminem being in a Super Bowl ad. I have listened to both Eminem and Ludacris. And Ludacris' lyrics are no where near as pro vocative as Eminems and yet he hasn't said anything about the Super Bowl ads. Not that I am aware of at least. I am not saying that Bill should ask for one. I just think he was silly for even trying to boycott Pepsi over Ludacris.
