The Muzies already have an autonomous region, the AARM, in western Mindanao. Most are pretty much isolated in a small area among the 7,107 islands that make up the Philippines.
I have yet to see a Muslim in my 5 years here on Cebu.
While I do not care for Muslims, we have to realize that they are all over the world, and probably as many, or more in the US as there are here.
The Philippines is an extremely devout Christian (Catholic) country. Every town has a Catholic church, many, if not most, of them are older then America.
From what I can tell, this sort of replaces the old agreement that set up the AARM, but the Philippine news reports I have read are rather sketchy on the details.
I see more an more of them up here in Angeles; not males, but a lot of girls with the hijab running little street stands.
