Nature abhors a vacuum. In the present context, the vacuum is the withdrawal of Christianity from life in the Western world. This vacuum of spirituality must be filled, and what may very well fill it is Islam. There are really only two probable outcomes -- either the vacuum will be filled by an altered form of revitalized Christianity, or it will be filled with conventional Islam. In any event, it will be filled. That is not in doubt. Mankind needs religion, and demands religion. Religion is not something artificially imposed -- that is simplistic nonsense. Religion is the collective response to an upwelling thirst for spiritual guidance and truth that never ceases. The idea that Western society will somehow outgrow religion is ludicrous. That would be like outgrowing the need for your liver. It won't happen, ever. So you pick -- will you have Christianity, or Islam? You probably won't get a choice, but you can have a preference. I pick Christianity, which is superior in most ways to Islam, except one .... Christianity has fallen, and Islam has not. That is a significant strength in Islam.
