I think you missed my point!
I don't like modern bumpers because they're painted - thus, bumper stickers can ruin the paint (a`la removal). So I certainly don't want to stick these things on the body of my car.
Even if its a magnet, there's still a risk you'll do something to the body paint of your car by slapping/peeling off the magnet even once much less multiple times. The less touchy, the better! I prefer sticking to bumpers. Having stickers *there* is ugly enough, anyway!
