I personally question Islam as a "faith." It seems more a political system. That said, there is nothing in The Constitution that guarantees the right to plot and murder any one. Tolerating Islam is a violation of my right to practice my religion and worship as I please, a right which I will defend with extreme force until I am dead.
Seems? Nay, is. And more - Islam is a lie. It is spiritual abuse. It is state sponsored domestic terrorism. It is religious intolerance. It is retrograde, God-denying, God-hating evil.
