They destroy non-Islamics. Then they start destroying each other. At some point, we are going to have to declare Islam as a cult rather than a religion; then we can outlaw and deport them.
and if you think any govt on the planet is going to deport these nice young boys, you need some medication. sorry to be harsh. these muslims are more valued citizens than you or i am. dont believe it? you just try burning 4,000 cars in twelve or so cities and see what happens to you.
Either that, or declare the Manson Family as a religion, and import the Amazonian Jivaro headhunter/cannibal tribe.
Level the playing field and provide for competition for mass murdering savages! You know,.... Capitalism!!!!!
