Thanks!
This is why I don’t think Western Civilizations will never have to genuinely worry about the muslims, they are hardwired to hate each other more than anyone else. They are truly a hate filled culture and because of their never ending focus on hate, they are destined to stay that way as in the 8th Century.
The only times they pose significant threats to us, is when they have the ability to travel outside their realm though (this time) oil money.
This language map is some help, but a lot of Sunnis, Shiites, Alawis, etc. speak Arabic.
