As mentioned before, as soon as George W. Bush had to take on Islam, liberals fell in love with the religion on a "the enemy of my enemy is my friend" theory. Later, when it was revealed their messiah BHO was born and raised a Muslim, that cemented their love for the Muslim faith.
As such, they are completely, and perhaps willfully, blind to the fact that Islam is at least, and probably more, intolerant than the worst backwoods bible thumper.
