Saw the same **** in Clear Lake on the corner of Bay Area and Highway 3. There have been other impeach obama signs, though mostly relating to the NASA lay-offs.
It used to work for Krishnas, people are often disoriented, distressed or bored waiting for flights or arriving home to nothing and nobody.
No matter what side of the isle you reside on, I think we can all agree that if you're spending your spare time hanging out at airports holding signs comparing the President to hitler.....well....it may be time to re-evaluate your life.
I don't want to interact with strangers in any of those states of mind, especially when the strangers have strong opinions about crap that they are determined to share.
I saw some of these guys holding signs on one of the overpasses on the way to Galveston one day, I think 646 or 517.
I think if you've ever used the words Hitler or dictator to describe one of our presidents, you should be forced to listened those who survived concentration camps describe what they went through and what happened to their loved ones who were gassed to death by the millions. Or better yet, give them a first-hand experience of what living under a dictator would really be like.
UPDATE: Video has surfaced of the OP walking through the airport terminal: (I think you know where this is going) Spoiler "Impeach ObamAAAAAAAAAAHHHH!!!!!!" <iframe width="420" height="315" src="//www.youtube.com/embed/f4CizzE-zZo" frameborder="0" allowfullscreen></iframe>
