This is the seed of radical Islam:
Thousands of Madrassas (schools) like this exist around the world; starting in the 1970's. In them, children are generally taught to take the Qur'an literally in a brand of austere Islam called Wahhabism. For all too many, this is the only education they will ever receive.
While there are numerous verses in the Qur'an that teach peace and tranquility, there are many that don't. Those that don't are based on the belief that there can only be one god in the world and his name is Allah; and that there can only be one religion in the world and that is Islam.
So, these children are taught that "unbelievers" (infidels) -- which, by the way, include modern day secularized Islamics -- must either be converted to fundamental Islam or be killed or enslaved. Thus, they are taken back to the earliest days of Islam under the Prophet Muhammad. A time when the Prophet, himself, spent the last 10 years of his life as a military commander in his effort to spread Islam through wars against Christians, Jews, and Pagans.
What should concern us all is the depth to which these Madrassas have radicalized Islam. In France, for example -- there are "No Go Zones" where the French government does not intervene and where Muslims are left to govern and educate themselves, and where support for ISIS is the highest of all other European countries. 27% of 18 to 24 year-olds, and 22% of the 25 to 34 age group support ISIS.
Simply, it is impossible to stop the radicalization unless the Madrassas are shutdown.
