They ARE inferior.
Yes, the conduct of criminal muslims is inferior to the one of most native europeans and the majority of americans.
However - seriously speaking - no human being is born inferior to any other one.
Followers of Islam should be respected on behalf of their belief as long as their behavior displays a will to promote human progress.
Brainwashed taliban soldiers have nothing of value to offer mankind. Turkish businessmen and malaysian engineers and that sort of "muslims" on the other hand might have and out of principle we must never forget upon that part of reality while whishing to defend true civilization.
There are muslims and there are muslims.
