Locker rooms are for changing clothes. I’d think it would be weird to see somebody praying in one in general.
There’s a time and place for everything...
Christians need to start praying the Lord's Prayer out loud in every public place, sing their grace* before a meal in every restaurant, and for Catholics to pray the rosary wherever they go. Everyone should hand out religious tracts and prayer cards, especially if they see muslims with their butts in the air, as I have in a Washington, DC restaurant. Let the ACLU atheists keep busy stamping out a ton of whack-a-moles. It is the ACLU's interference since the 50s to quash Christianity that has made this muslim incursion possible.
