Sounds like some sniveling, liberal bedwetter in the Dayton airport’s IT department has gone into the political censorship business; pretty typical for the type. They can’t stand the thought of free political discussion that doesn’t agree with what they think. You probably wouldn’t have had any trouble at all getting onto Democratic Underground, Daily Kos, or the Huffington Post.
A tip: If you are ever blocked from FR immediately test the DU and dKos sites.
