Islam is “religion” based on cruelty to the unbeliever. Unbelievers can be other Muslims from other sects of Islam or non-Muslims. Muhammad was a child rapist, slave trader, slave master, sex slave trafficker, kidnapper, genocidal mass murderer, blissful torturer, thief and liar. This and more is well documented in the Koran and Hadith.
The Muslims joining ISIS are just Muslims wanting to be “Good Muslims.” They want to follow the way of their prophet. In the exact way Muhammad lived and ruled. No amount of sugar coating or mumbling about “moderate” Muslims will change that. “Radicalized” Muslims are simply Muslims who want to be “Good Muslims” in their host country according to the very same Koran and Hadith.
