Islam is incompatible with the US Constitution.
islam is incompatible with the concept of nation-states. It is also incompatible with civilized societies. In fact the ONLY reason that there are islamic countries that have some semblance of civility, is the effect of European and American colonialisation in the 19th century. The colonisers removed the most virulent aspects of muhamedanism by brutal force, ‘civilising’ the religion. With the end of colonial occupation after WW2, the virulent aspects are free to expand.
