I don't think running a protection racket is the best way to get your point across. "I promise never to watch a movie until my demands are met" might actually carry some moral weight.
It would be like saying "I won't walk outside until the city cleans the streets!" It's a promise a majority of people simply won't, or can't, keep.
What I did say is that suggesting the American populace stop seeing movies if they don't like the treatment is silly. The American populace isn't going to ever stop seeing movies.
It wont happen, and so suggesting that it happen is moot.
