Thomas has an excellent post over at Infidel Bloggers Alliance. Crisp, clear and to the point.
Virtually everyone in America, Europe and the Free World shares a single idea: atheists and evangelicals; Platonists, Greek Orthodox and Amish; Hispanics, blacks, and WASPS; Baptists, Catholics, and Marxists; hedonistic materialists, party girls, and comedians; Filipino postmen and Dutch engineers; gays, feminists, and High Church Anglican grandmothers. However, it is the nature of our times that this idea, shared by nearly everyone you know and nearly everyone they know, an idea our ancestors believed going back millennia, cannot be spoken in the public square.
This idea can be stated in many ways but it’s basically this: “Allah does not exist, Muhammad was not his prophet, and the Koran is not a holy book.”
Go read it all, for it's a great piece.
If Muslims cannot accept that most people do not believe Allah exists, do not believe Muhammad was a divinely inspired prophet, and do not believe the Koran is a sacred book, then we really are in a clash of civilizations. If Muslims in Pakistan cannot accept that the Catholic Pope will occasionally, without even trying, insult and deny Islam, then we are in for a long and terrible conflict.
