Shoot, you guys have it easy. I work in Vermont, and live in western Mass, near Northampton and Amherst. When the fruits start anti-nuking me, I ask what they do. Then I generally get to state " I no longer argue technology with Art History majors, it hurts my head" and walk away.
But really, even here, I have found most people are open to at least discussing it, and as long as I am patient and knowledgeable, I find that at worst, we agree to disagree. Like BZ, I represent my employer wherever I am, and being obnoxious does nothing beneficial to our operation.
