We are not at war with Islam (it is probably unconstitutional) but we are at war with SOME Muslims not all.
As to the refusal to understand the nature of Islam I would put most of that at the feet of the education system. Since the Catholic Church has had periods of violent repression of dissident groups it is easy for the duplicitous to equate the behavior of the Church (500 years ago) with that of Islamists today. So the argument that one of the pillars of Western Civilization was just as violent can only be refuted by those with some actual knowledge of history. They are quite rare in this society.
I still maintain that the best way to refute Islam is to actually read the Koran. It is hard to get through being nonsense filled and all but I read it in the crapper where I had no choice.
AS a country, we may not be at war with Islam, but we should be. I don’t know, exactly, why it would be unconstitutional.
However, as a civilization, we most certainly are at war with Islam, and will be till either they, or we, are destroyed. Sorta lie the Palestine/Israel situation. One will win; one will lose.
