Are Jews the only ones scared of terrorists?

So a whole buch of people here know I am Jewish. "B" told me that she had mentioned it to a few people (and the Lebanese loooove to gossip). One person, "R", who is mentioned in an earlier post, I heard figured it out, or at least guess that it must be the case that I am Jewish. How, I wondered. The answer, and I am not making this up, is because I seemed to look worried while we were driving through Hezbollah territory. (The tribble episode of Star Trek comes to mind, where the agent was found to be Klingon because of the Tribble's natural aversion to Klingons. ) I assume that most American tourists calmly accept the fact that they are driving through a genuine terrorist stronghold with more grace.
