I don’t usually answer such questions, but anyway well Muslims don’t fight over anything, they fight over what they believe needs to be sorted. What they believe is right. And why do you always go after attacking their religion? If you know someone or certain people don’t like it why do you carry on doing? The problem is not them but people like you, who can’t leave others alone.
Jokes are not a problem, but has to have it’s limits and it must not have anything to do with religion. Religion is not something you take like a joke. It’s serious for those who believe in God.
As far as Prophet goes, let me put it this way; If someone disrespects your father or someone you love, would you let them? I don’t think so. We are told to respect our Prophet and many who came before Him.
Just leave them and their religion ALONE. Is that too much to ask for?
