Rhubarb I am sorry again but what people carry inside themselves isn't always what the ideas were in the first place. With a book the words of which aren't changed we can always go back and check that the ideas haven't been modified with time.
Muslims are upset and do protest about the fun being made of God, and we are puzzled why the Christians have taken it lying down.
As for the prophets (all of them), we find it wrong to draw their pictures, and we protest about them, too. We are hurt and do protest if Jesus (pbuh) is depicted in a scandalous manner.
The difference between the Jews and the Christians is that of recognition of Jesus. The difference between Christians and Muslims is that recognition of Muhammad (saw) as a prophet (the last one, and of the status of Jesus (pbuh). The difference between Jews and Muslims is that of the status of Jesus and of Muhammad.
There is also a difference of the nature of prophets.
When the prophet is depicted with a bomb on his head, when he is depicted as guarding the entrance to paradise and saying that it has un out of vrgins, what does it prtray? What is the message?
The message in these charged times is for the non-Muslims to fear their Muslim neighbors, and for the Msulims to feel that they are being labelled as terrorists.
It isn't just going to Paradise yourself with your beliefs and with your good deeds, it is also about "spreading the Gospel", if I may use the phras from Christianity.
Do you want your children to have a certain code of behaviour? Do you want a certain beleif system or do you believe that all paths lead to salvation or to bliss on earth? Do you believe in certain politcs? etc.
If you do, do you want peaceful discussions about those beliefs, or do you think shouting and abuse will egt your point across?
