They're intent on taking over public life in America, right now, hence all the anger at Muslims at large.
The question is how to fight the evil, radical nature of Islam as strictly interpreted and still adhere to our Constitutional principles for ourselves, as well as Muslims who mean us no harm.
How is one to accomplish such a feat?
I am not familiar with a well known intent to take over America (by most American Moslems) and more importantly, I am not aware of any great risk that such an attempt can be successful.
Again, IF Moslems will become a disruptive element in our society, their emigration should be limited. At present I believe they are at most 1% of the population, therefore in no position to take over.
