They are devoutly following their prophet. They are not “radicalized”.
Muslims have a religious duty to kill, convert or subjugate all non-muslims.
Everywhere.
Forever.
They’ve been doing it for 1400 years.
For a muslim to freely practice their religion, others must die.
Mad Mo made it so.
If there are moderate Muslims (which I doubt), they are heretics according to their guide for life, the Koran. ISIS is Islam, and Islam can’t coexist in peace. It is incompatible with freedom and must be banned in non-Muslim countries.
Here, again, my solution - ban Islam, close mosques, deport Muslims, bring US troops home and put on our borders, institute a “pet the pig” requirement to board a plane or enter a non-Muslim country. Problem largely solved.
If they want their Sunni/Shia fight, let them have at it in their own countries as long as they want. There are no Muslim good guys, and the US is stupid to get involved.
