Have you ever eaten with one??
Taking the question as non-rhetorical, I have never broken bread with one. One was in my PCP's office and did see me on occasion for minor things like colds. After 9/11, I asked that he be removed from his rotation. As it turns out, so did the majority of other patients. He then scurried back to Pakistan since virtually no one wanted him to touch them.
I have. One of my college profs was a Muslim who one time invited the whole class to his apartment for dinner. I went. He was a great guy. But he made it clear he did not want to be associated with the "crazy" (his words) Muslims from the mideast. He was from eastern Asia.
