I just don’t see your evidence that “all” Muslims want sharia law. Alot sure... most maybe... but certainly not “all”. The point is people in this country get all freaked out by the boogyman that is sharia law. It will never happen here.
Boogyman? Seriously? It is already happening here (there are areas in Michigan under nominal sharia law). It already controls small enclaves in Europe. It is a simple matter of immigration rates and relative birth rates.
If a sunni or shia tells you they do not want sharia law they are either engaging in Taqiyya or they are apostate. The central goal of islam is not mass conversion but rather the imposition of sharia law. So yes - ALL.
It will never happen here? Why? You think Americans are special?
If I told you in the 1930’s that there were going to be gay pride parades in SF where men would bugger each other in public - you would have told me - it will never happen here.
