I was in my Education class today and we were reading about students' freedom of expression in school. We came upon the topic of students not standing for or saluting the flag because it's against their religion. I'm only a freshman in college, so I still clearly remember how some kids chose not to stand every Monday during the national anthem. They *said* it was against their religion, but these were generally the slacker kids who didn't really care about anything and thought they were cool because they "rebelled" (and I knew one of the others was a practicing Jew, as our family had been invited to experience Passover with theirs, as we are not Jewish).
My question is this - what specific religion prohibits standing for or saluting the flag? It's just that I've never heard of any and that I can't think of any, and I'm curious.
