There is a huge, basic incompatibility between Western culture and Islam. Wester culture is accepting of any other culture. Islam is not. To adherents of Islam there is only one way; or, they kill you. If Western culture is to survive intact, it must either convert Muslims to other religions, or, kill them. Neither is something Western culture, especially the French, is willing to do. So, the West will continue to bleed until it either dies or kills/converts Islamists. When will Western culture reach that tipping point? Probably after millions of Western innocents die. Not a moment before then.
I watched the movie ‘Fury’ recently. Thought it was good. One deeper point of the movie was how committed the SS was to killing us and getting that point home to new soldiers being called up to the front. We need to be thinking now about decisions we may need to make, just like our forefathers did.
Add to this that it also applies to the different versions of Islam. Sunni Islam and Shi'a Islam are, throughout history, antagonistic and even deadly towards the other.
However they both have the doctrine that there is no backing out of Islam, either individually or geographically. To renounce Islam to become a believer in any other religion is a death penalty in many Islamic-controlled countries. Geographically, if Islam has ever conquered a place, it is a religious dogma that it is theirs forever. Thus Islamic clerics demand that Spain return to Islam, amongst other places.
Finally, for this posting, there is this absolute status demanded by Islamic believers, that the entire world must subjugate to Islam even when practicing other beliefs. It is not just these cartoons in France, any media or speech that denigates or criticizes Islam is blasphemy and punishable by death.
