The plot for 24 has drawn much criticism for it's portrayal of Muslims as terrorist. Personally, I don't know why people are shocked. 24 isn't the first or last media representation of Muslims in this manner. Furthermore, we are talking about the FOX network. What more do you really expect from the home station of Bill O'Rielly? I don't think that this one show is going to make people suddenly wake up with an epitome and say "Hey, I think that all Muslims are terrorist!". People who feel that way, felt like that before the show started and those who use it as a pretext for their bigotry would find another vehicle to justify their views if the 24 plot was different. The bottom line is, that to effectively combat negative stereotypes we let our neighbors know that we are Muslims and be exemplars of Islam. Other than that, what can you really do besides give more publicity to the show, and all publicity is good publicity from the show business point of view.
