All the muslims I know are upset by ISIS.
ISIS kill far more muslims than another people!
And If muslims were really sleeping terrorists, a country like mine, France, with its 10% of muslim, would be constantly on fire and blood.
And we was attacked, not by foreigners, but by insiders... not by real muslims, but by lobotomized recently converted muslims (who was drinking alcohol, smoking and dancing in night club only 8 months before the attack)
