Why stop at revoking citizenship? These are individuals aiding a terrorist organisation bent on genocide, ethnic & religious cleansing, that uses rape to terrorise and which practices slavery. Revoking citizenship merely makes these evil men someone else’s problem; they ought to be at the least imprisoned or interred.
Good! This is probably not only a necessary step for Indonesia’s national security, but is also an important realization by an elected government in an Islamic place that if it permits its internal Islam go wild, it WILL go W I L D!!!!! The more governments we have saying “Nope, you ARE NOT bringing that radical crap here”, the better—-for those countries and for every country. There is nothing better than Muslims riding herd over other Muslims.
