Yeah, the magnolia flag actually incorporates something the state is known for. (I suppose a flag with a noose is out of the question.) The flag with the waves and pinstripes...frankly that wouldn’t have made it to the finals if I were choosing.
The thing is, "trust in God" --or more commonly, "in God we trust"-- is not in itself considered evidence of establishment of a religion. I always just mentally add the old punchline "... all others pay cash" and be done with worrying over whether some guy clerking in the convenience store assumes I'm religious when I hand him a dime.
If Trump is re-elected though I might start inspecting dimes to make sure they don't start saying that we trust in Trump.
It is kinda sneaky if Mississippi might be thinking about telling people to trust in God on its new flag, instead of just assuming we already do.
