"Choose Life" — the license plate... the Supreme Court case.

The way Adam Liptak puts it:

Had the states not decided to make license plates a forum for a sometimes comical array of messages, the “Choose Life” cases would easy. But many states have turned their motor vehicle departments into a kind of souvenir shop. They may also have given up the right to decide what gets sold in them.

Mm... yes... it's called "free speech," and much of it is foolish and/or opinionated. Religion is one more category of expression. Deal with it.
