You’re correct in that the true nature of Islam is as a unified religious and political system: a theocracy. That it hides under the protections affored to other religions, based on our founding principles of englightened western Judeo-Christian tolerance, is a terrible problem for us, and one not easily solved.
Sadly more Muslims understand our laws, and use them to advance their agenda, than many Americans. They are well prepared when they come here, and if not they are taught how to oppose us in their Mosques and Islamic centers in order to keep their political ideology moving right along.
Islam is clearly incompatable with our Constitution. And we see many attacks against our Consititution today. Break it down and inroads of all kinds will slither in. Attack our Judeo-Christian values and this too will open the gates further and further.
It is heartbreaking to see what we never would have imagined possible by our elected officials....and times running out to stop this.
