Not all of them are. My hairdresser is a Muslim, originally from Iran. Escaped there because there was no freedom for women, and is a citizen here now. Couldn't be a nicer person. Doesn't care what religion her clients are. She's pretty secular herself. Celebrates Christmas. My pharmacist is also a Muslim, originally from Syria, but has been here for decades and is a citizen. Wonderful loving guy, gives me a hug when he sees me, prays for me, wishes me Merry Christmas, knows I'm a Christian and has nothing but joy in his eyes when he sees me. Fearing all
Muslims is irrational. I have yet to encounter one who is dangerous or a xenophobe. There are quite a number of them wandering around in my city whom I don't know, but they all seem like decent contributing citizens and not the type you're describing.
But...I do agree with Nicholas Kristof that Saudi Arabia is a backwards nation.
