The difference is that in the west we try as much as we can to separate church and state, because everyone knows that religion is the main reason for wars and killing and hatred, and has a very long history of persecution and injustice in the name of their Gods and beliefs.
The risk I see with the Muslim religion is that their religion comes before state, it is their law, and their religion and law are one. Not only that, then want it to supersede our own laws and use our constitutions as grounds to implement their own religious agenda.
But by saying this we are considered to not being politically correct, and we certainly would not want to offend anyone.
WRONG- religion doesn't do anything, it's warped people trying to use religion for nefarious activities!
