So Florida is considering a vanity plate with a christian message (’I believe’ and a cross).

Of course, many might not see this as crossing the church/state divide.  But those arguments collapse thanks to this telling line:

[Rep. Edward] Bullard, the plate’s sponsor, isn’t sure all groups should be able to express their preference. If atheists came up with an “I Don’t Believe” plate, for example, he would probably oppose it
