Consider the heavily Persian part of Los Angeles, known to expats as "Tehrangeles". It's hardly a bastion of Shariah law, as Muslim as Miami is communist:
It is strange to me to see and meet so many Iranians who are smart, well educated and Muslim in name only who were ruled by what is seemingly a smallish percentage of Muslim thugs. I don’t know what it is in their make-up that can let that happen - they seems far more interested in doing business and/or getting a better education than to fight off those who put them down!
