While it's fun for some to mock part of someone elses religion and I absolutely advocate free speech we need to see this as what it is. It's trolling. If you want to stick it to the extremists then do something the moderates can unite with you against them. No moderate could support EDMD because it specifically goes against the teachings of one of their holy books.
Rather than ask for a response that a peace loving muslim might give an extremist muslim, ask yourself what a peace loving Christian would give by way of a response to an extremist Christian should Jesus be mocked. There you will find your answer.
Interestingly (or perhaps not) this doesn't just apply to Mohammed. This applies to all prophets in Islam, including Jesus and Moses. It's because idolatry is the worship of something other than god and to muslims there is only the one god, although he's the same god as the god in all Abrahamic faiths, just interpreted differently.
The same way Christians should be constantly and publicly apologetic for the crazy abortion clinic bombers?
My impression from Muslim friends is that they do, but internally - and I can't blame them. Muslims face an increasingly cold attitude from people in America, and unity against the face of discrimination is important. Without speaking from personal experience, I suspect that nobody wants to get into an internal witch-hunt (who's the extremist bomber?!) that will simply fracture the community.
Perhaps they would be more willing to speak out against extremists if they thought the rest of their country had their backs. But let's face it - looking at this discussion (and knowing that attitudes in the general population is markedly worse), we don't. The moderates are between a rock and a hard place - on one side a public that fears and loathes them, and on the other a bunch of murderous fiends that look like them, and claim to be one of them.
The French got their church out of their daily lives -- and don't seem exactly nostalgic for its influence... I'd guess they use the term to mean that they come from a culture with Christian influences.
(I call myself "Protestant atheist".)
As a Christian I certainly don't like Jesus constantly being mocked -- but I also think he is perfectly capable of defending himself. Christianity has a clear response. Jesus is our hero. When he was mocked, tortured and murdered he laid down his life. Most of his closest followers died in the same way. The whole question is central to Christianity.
Does anyone have any examples of a concise response that a "peace-loving Muslim" might give to an "extremist Muslim?" ... why do more Muslims not speak out more often against extremists?
