The left might not like the Muslims if they knew Muslims believe Allah will bless them if they try to kill homosexuals.
If only that would be the case. BUT, it is not. The left ignores that fact along with all of the other aspects of Islamic extremism, simply because all of the pet causes of the left, save one, are nothing but tools to be used and discarded when their usefulness has ended. That "one", the destruction of capitalism, with the installment of world socialism, allows them to be hypocrites in their own shameless eyes. All we can do is hopefully persuade the uninformed of these facts, and win them over...
That, of course, is assuming the Left has common sense. I can assure you that they do not. They are too entrenched in their idealism and fantasies of living in the Land of Ought-to-Be. They want to create Heaven on earth using Humanism as the way.
That said, it wouldn't surprise me one bit if San Francisco is next on the terrorist hit list, considering the large gay population in that city.
