We need to deal with Islam the same way we deal with Communism and Nazism. We don't outlaw those either, they also want to overthrow the US Constitution and replace our government with a totalitarian form of government. Islam is at least as much a political ideology as it is a religion.
That's been part of one of my standard rants for many months now. Maybe a year.
We're dealing with an evil, totalitarian, dictatorial, murderous political system masquerading as a religion. Just the treatment of women in Islamic societies should tell you all you need to know about this "culture". Add in their intolerance of non-believers, and it becomes obvious what a rational tolerance policy might look like.
Personally, I will become tolerant of Islam when there are churches and synagogues in Mecca, Medina, Riyadh, Islamabad, Karachi, Cairo, Khartoum, and similar locales, and the locals aren't trying to burn down the structures and kill the attendees.
Until then, they should not be considered a religion.
