I dont stare at middle eastern guys, I'll tell you that right now. Am I afraid of terrorists? yes, but I figure if these guys have gotten through security and everything, then our suspicions will fail to produce anything without further suspicious action from the person being observed. My definition of racism involves hate. I would say maybe you're scenario is one of fear more than anything else. Plenty of people stare at South Asians, the majority of which are Hindu, but those staring don't know the difference. Sikhs getting profiled? Fear and ignorance.
