you can trim off the bottom of the sticker, removing the moveon reference.

I agree that their name has baggage.

It also gives people a place to go for more information, so who knows which would be better.

I guess I would come down on the side of leaving the MoveOn part intact, because the sentiment on the sticker is mainstream, even if the name MoveOn means "liberal" to many people. Maybe they'll start to realize that "liberal" IS mainstream.
