The basic problem here is very much like that of WWII. We have had Germans in this country for so many generations, that any attempt to draw parallels between them, either culturally or religiously, and the Muslims is doomed to failure. Germans are one reason why we won the War of 1812. They were technocrats then as now, and brought rifled musketry to the backwoodsmen of the frontier. They are culturally and religiously completely homogeneous with the Founders. And nobody talks about "German Americans."
By contrast, the immigration and appearance of Muslims in this country happened so fast that it took most of us by complete surprise. The problem is that they are 1)Outside the "Judeo-Christian tradition" -- WAY outside. 2)They do not in general identify with our culture and are seldom at pains to deny the fact, and 3) Do not understand the values of the land they have immigrated to. They honestly believe that our beloved America is a mutual arrangement whereby people can make lots of money with no sacred mutual bond of patriotism or sacrifice.
The Quran is a scary document. Recently a victim of the Taliban turned up missing his left foot and his right hand, a truly sick and sadistic thing to do to another human being, a great prototype for "cruel and unusual punishment." When asked where his tormentors came up with this idea he said "Oh it's right there in the Quran."
In other words, God wants people to do that to each other. Nowhere in the document are these people admonished to have anything but contempt for unbelievers, although "people of the book" i.e. Jews or Christians may be spared for purposes of conversion, if you're neither of these, you are to be MURDERED, pure and simple. God says so. Their claim to being a mainstream religion is bogus. And their claim to Jerusalem as one of their sacred sites is ludicrous, based solely on a dream Mohammed had about riding on a mythical animal called a "Borak" all the way to Jerusalem and from there up to the seventh heaven to have a chat with the Creator of the Universe. In his lifetime he described it as a dream, but in the lore of subsequent Muslim teaching, it's something that really happened. Nonsense. But since Mohammed could neither read nor write, what can we expect?
The situation is hopeless. Pat Buchanon is right. We and they cannot live together, and if we persist in our multi-culti fantasy about Gentle Mohammed Meek and Mild, we will wake up very very soon without a culture, without a civilizaton and without a country.
All the best, Maturin
