I don't think insulting people or their religion is justified. If there wasn't any insults, we wouldn't be here today. The problem is really quite easy to solve.
Admirable trait. Very libertarian, and I agree with you, except it really doesn't solve the problem regarding many of a certain faith who have essentially said to convert to their faith or die . That has nothing to do with insults, I'm afraid.
Regarding your stand: Perhaps you should start a letter writing campaign to Hollywood. I don't know if you've noticed over the last decade or two, but it's almost impossible to watch a single show that doesn't insult Christianity any more. It has become quite fashionable to bash Christians and all things related to Christianity. Just read many of the leftists post in ET. Same thing.
