Lets examine an analog, and see how you'd feel about it. We're looking at a movie about oppressed race rising up against the oppressor, and an actor of the oppressed race making a quip about taking revenge on the oppressor.

Inglorious Basterds was a movie about a group of US Army special ops crew, among them a couple Jews, and their plan to take out Hitler. If you saw the movie, you know that the Jews prejudiciously slaughtered hundreds of Nazi soldiers and Nazi sympathizers. (If not, sorry bout the spoiler.)

How would you feel If the guy playing the Jew in question made the same joke in the same context, at the same venue?
