I believe you're right...
Among the Left, Islam is "chic" and Righties are afraid of the Multicultural police to say out loud what Mohammedanism really is.
Here's how I see it.
Many on the left support drastic population control and decrease. Many adher to the 500 million rule: that earth can only safely handle this much humanity. You here this mantra constantly here on the left coast. Islam is the culture of death, openly advocates and practices putting to death of millions in the name of their religion. How better to acheive the left's aim then directly using this religion to attain this goal.
The left practices denial and narcissism. They think they won't be among the unfortunate that are killed or sacrificed.
Meanwhile, when it's all sorted out the left will be left with a world filled with mostly liberals and lots of oil.
Like I said, you actually here many liberals expounding on this simplistic nonsense here on the left coast all the time.
