It's real hard to do that if you have kids. In our case, we do have secular/cultural decorations but also have the TV tuned to EWTN. And the Nativity scene displayed prominently.
Several years ago American Atheists threatened to sue the Panola County Mississippi School Board near my home because every football game at South Panola County High began with prayers. Guess what? The good Christian families ignored this hatred and continued to pray before every game. The word around town was there’s not enough jail cells or lawyers to keep us from praying when and where we wish.
Also I recently served on jury duty at the Desoto County Courthouse in Hernando and every session began with prayers by the judge.
God Bless the Great State of Mississippi!
