As far as I can tell it sounds like a pretty fair program. The state is simply giving individuals and groups a unique medium for expressing their beliefs.
I read that, and it seems fair enough. However, I can imagine some messages being deemed inappropriate, and some actually being inappropriate. Who will judge, and who will draw the line? In that regard, I would think that it is in the state's best interest to chuck the idea and let people address these issues with bumper stickers and magnets.
That's a good point...I hadn't thought that far ahead.
As a practical matter, it probably would be easier for all involved to rely on bumper stickers. Except of course for politicians, who can score easy political points from their support for specialty plates.
