ROFL! You say the dumbest things. Does that mean all Muslims are required to kill anyone who isn't a Muslim?
They aren't required to, but they are allowed to, if you are stopping them from doing God's Will.
In a perfect world that might be how Islam should be practiced. Unfortunately too many people who are or that converted to Islam are taught through sermons to hate, fight, kill and destroy in the name of Islam. People are convinced that killing is not just permitted but expected by allah, even other muslims, including women and children. They can blow up mosques, burn qurans, rape and torture captives, behead and even burn alive those who they are told are the enemy. They are told peace will only come when all the world are muslim and living under a caliphate lead by a mad man.
They can commit atrocities and violate every precept of Islam but those who are not muslim or a differing sect and ideology of Islam are not permitted to question Islam, joke about Islam or Mohammed or speak against a muslims. Everyone should conform to ancient or misunderstood ideas of behavior or what they are incorrectly told are laws.
There are kind giving peaceful muslims in the world but they are the quiet majority. They should be speaking out and disavowing in the strongest terms those giving Islam a black eye.
Too many are "practicing" Islam as an excuse to violate every moral, common sense and law of man kind and doing it as some mandate of Allah.
