In re Talladega Nights

If a Hollywood film satirizes a stereotype with the knowledge that the majority of the audience will see the depiction not as satire but as truth, is this equivalent to perpetuating a stereotype?

All this is just to say that the Clerksville viewer reaction to Sacha Baron Cohen's character in The Ballad of Ricky Bobby was sort of disturbing. This was at the same theater in which I saw Brokeback Mountain a few months ago, but the audiences were obviously very different.
