Outside of caging for life or executing, what does a civilized country do with such animals?
You send every one of these cult worshiping barbarians back to where they came from. Every Muslim is commanded to kill, harass and convert infidels. Along the way, they are allowed to rape you wife, your daughter, your mother if they want to. They can enslave you children as sex slaves if they want to.
And they can cut off your head if they want to. It's right in their Koran. Hussein Obama called it the Holy Koran.
