We actually have quite a few Muslims in Massachusetts. Most of the time, they just glare at your or avoid making eye contact. Not the friendliest bunch, that's for sure.
So you are admitting you don't know any Muslims. How do you know you're being glared at by a Muslim? Do you smile and say "hello"? Try it.
Oh? And how many Muslim immigrants do you know?
Only a small handful of 1st generation immigrants. They're my friend's parents. I dated a Muslim woman for a short time 20+ years ago. Her parents were immigrants. I got to know some of her family, also immigrants. I served 20 years alongside Muslim American Coasties, not many, but a few as well as some in the TSA. Now that I'm in local county government, I work with Muslims all the time. Know what the difference is between the Muslims I know and love and the Jews, Christians, Buddhists, Satanists, atheists, agnostics, Wiccans and, yes, even a Hari Krishna I know and love? A lot of things, but it's not their patriotism.
