My "projections" have clearly stated, on this thread and others, that increased secularization and/or lower Muslim family sizes would impact the numbers.

The problem is, there is absolutely no reason to believe that second and subsequent generation Muslim families will be smaller, or more secular.

The larger family sizes from past generations of immigrants were largely a function of, and enabled by, the large demand for labor - farm and factory. No such pressures exist today.

As for secularization, the European experience offers absolutely no evidence of a move towards secularism in their Muslim communities. In fact, as evidenced in a recent poll of over 100,000 British Muslims, many of the younger generation Muslims actually have harder line anti-western -liberal attitudes more in line with fundamentalist Islamic beliefs.

My "projection" as you disparagingly refer to it is at least based on objective numbers. Your "suppositions" are just wishful muddle headed liberal thinking.
