Honestly, it possibly is a bit racist - making assumptions based on probabilities and stereotypes.

I am and have been friends and coworkers with several people who were from the ME (muslim and not) and they were decent folks. There was one notable exception (ex of one of my friends) who turned out to be a real piece of work. I’d like to think that by being aware of my prejudices, I can disprove them by informing myself about people, and at least not writing them off until I’ve made myself aware of who they really are.

Either way, if I had a daughter, I hope I’d raise her well enough to be able to trust her to judge these sorts of things on her own once she became an adult.
