Nowaynohow - We are ALL individuals who are ALL entitled to believe in/not believe in what we choose without derision.
No, really nobody, and certainly no institution is entitled to be protected from derision, mockery, sneer, snark etc...that is the price, and the beauty of living in a free society.
Of course there is a time and a place. It would be rude to go to a church wedding and start talking loudly about 'imaginary friends'. It would be rude to walk into a mosque with your shoes on and a picture of Mohammed on your t-shirt.
But there is no good reason why books and newspapers shouldn't contain pictures of Mohammed, why people shouldn't write jokes, songs, parodies and serious critical books about religions, or why people on a discussion forum like MN, which is irreverent about most things should be expected to be particularly respectful of religious language.
The idea that religions should be immune from derision is dangerous and scary.
