I've seen graphic licence plates for everything from sports teams to square dancing. As long as any non-profit group can apply to get their logo on a licence plate, I don't have a problem with a religious group having the same privilege as similar secular groups.If that's the case, would you be ok with the government selling Bibles in courthouses or other government buildings? If you allow religious license plates, it opens the door for other religious items to be sold by the government.
