Firefighters disciplined for Merry Christmas billboard

[Vlad]

 
Lancaster Oh. fire fighters disciplined for doing something nice.

However well-meaning the sign was, its "Merry Christmas" greeting violated the separation of church and state provision in the U.S. Constitution, city officials said. Governments may not show religious favoritism or partiality, city Law Director Randall Ullom said in a letter to Fire Chief Dave Ward.

Aside from the fact that there is no separation of church and state provision in the Costitution, do the the actions of these firefighters endorse a religion? 
Do you believe that was the intent of these men...to endorse a religion?
I don't.
