Yeah. How can an open society tolerate a religion that doesn't tolerate the practice of other religions? I say it's an impossibility. We can only support a Mohammedan minority that is a substantial minority. Once the Mohammedan minority becomes sizeable, our society will become unstable.
We can tolerate intolerance, as long as it conforms to certain limits. Voluntary segregation, as opposed to Jim Crow laws, for example.
