While I was in college I became friendly with 4 or 5 Muslims from Algeria. These men hated, I mean hated to the depths of their souls, the United States. I came to realize that they are completely rational based on the strength of their hatred and contempt for the United States. In understanding this it became clear to me how they could come here and go to school, form "friendships" and see the goodness in Americans and feel absolutely no connection to our humanity. It is frightening really, I think we would call it sociopathic in this country.
Unfortunately, 99% of Americans can't even fathom this.
The good folks of this country must learn to get ugly, real ugly, in order to fight this satanic influence and win.
What you describe in your post is a good description of the islamics in the booths. I think I said they were cold. They looked at me with an iciness at one fair that made me tell my husband later that I was sure they were hating me for being a woman and not wearing a veil and for having the audacity to question them.
