Because the Almighty cares what sticker you put on your car's license plate. Doesn't have anything better to do, really.

This is more news about Christians falling all over themselves to prove how Christian they are to other Christians, and make those of us who don't follow their particular narrow worldview of evangelical exhibitionism know that we are doomed to the Fiery Pit.
Of course some of them are going to be agitated that they'll have to render unto Ceasar what is Ceasar's by paying a $1 fee for the "In God We Trust" sticker. Customization always costs, though some of these folks would have you believe that not printing IGWT on ALL THE PLATES is somewhere in the arena of Christians getting thrown to the lions. There goes the government again, persecuting Christianists by not requiring every single car owner to agree with them.
There is, of course, little outcry that no non-religious sticker option yet exists. Because, you know, a lot of folks have bigger concerns in their lives. The end result? The Georgia DOT got the plate designs it wanted.
