What's the difference between a joke and an insult?
A joke is aimed at someone else.
"I think if they want to protest movies, there are a lot of other movies to protest that do a lot more damage to the black community," Lee said. "There are strong images and more egregious affronts to (blacks)."
As for whether the producers, director, writers, stars, etc did something wrong...*shrug* I suspect it falls under the category of jest, and as the article states, the other characters condemn the speaker for being disrespectful. This is the sort of writing that used to fall under the category of humor, possibly even political humor. Now it seems as though not towing the line will get you a reprimand and demands to cut the offending scene out of future releases. So remember kids: freedom of speech is a-okay, as long as you don't say anything unpopular.
