We have to remember that President Bush can not jump on every bandwagon that comes along. He is the President of all Americans and has to mend fences outside of this country. I can make the position of both men fit in my outlook. We can not, though, continue to be a blindly "welcoming" country as Powell puts it. There was a time when those coming to our shores wished to become Americans. Now they come wanting to make America into what ever wretched pig sty it was that they just left.
I have had several Muslim students in my classes, and they are by no means monolithic. Some Pakistanis like us a great deal; most Saudis don't. (I know: why they hell don't they leave?) But think of it this way. How many "Catholics" in this country practice birth control? Are they still "Catholics?" They say they are---they just don't agree with the Church over that issue. You can make the same case with ANY Protestant church. I was born a Baptist, but I (gasp!) danced! So what the religion SAYS, and what some/most/many of the adherents BELIEVE it says are two different things.
Given that, Robertson is 100% correct about what Islam SAYS.
