Well, it is an outrage most certainly, but as a strict Constitutionalist, it is protected under the First Amendment.  It certainly is despicable that these atheists feel the need to do this, and the anger they demonstrate is almost palpable.  While they may feel offended at the site of Santa Claus, or Jesus on the Cross, I am deeply offended that they have taken out this billboard. I, for one, would never try to shut down a display of a Menorah.

We are citizens of these United States, and as such we should be understanding of people's customs, traditions and religious beliefs, as long as what they are doing is not illegal.
