Honest to God: my money is on the Leftists being able to subvert Islam.

There's also rampant homosexuality, pedophillia, incest, and authoritarianism in muslim countries and populations already. Those are easy avenues of attack for Queer Revolutionaries. Islam is not good at resisting subversion. It's used to attacking potential enemies with unlimited violence at all times, but the Left are always prepared to exploit that.
