Why does the freedom to "discuss all religions" mean that those discussions have to be respectful?

Who would determine what is "respectful"?

The Canadian media has already self censored for years on many topics involving Islam, including the shameful refusal to reprint those famous Danish editorial cartoons that so incensed Islamics.

The fact that you felt compelled to say that "religious satire" is part of freedom of expression in one part of your post, and then back down by saying criticism or discussions of religion must be respectful, is most revealing.

I wonder what Salman Rushdie would have to say on the topic of satire as applied to Islam?
