There is one of the stupid complaints about the flag going around on Facebook, and I was wondering if you can help me find some answers?

From this article.

First, why would it be illegal to fly the Gadsden flag?

Second, is there really a federal code that prohibits any flag flying higher than the American flag? When I googled the city ordinance section 110–131 it only came up with one viable hit, and that pertained to signs in a town in Florida. The other links were all tea party outrages.
