Many states either have or are considering license plates the cater to the Christian crowd. Indiana and North Carolina offer a plate with the words "In God We Trust". FL is considering license plates with a cross and stained glass window with the words "I believe".
Here are a few samples
Florida rejected this design but it is the current design being considered by South Carolina.
So, the big question is: Do these plates violate the separation clause?
What do I think? While this is not something I would make a case over, I find it somewhat disingenuous that these states are claiming that they aren't showing any preference towards Christianity with these plates.
I'll post more as the discussion grows.
