That's fine. I don't put bumper stickers on my vehicle. I sure as heck don't want some Commie lib doing it. I was talking payback. Nothing really political about it. Let them peal the sticker and all that glue off. That was more or less the point I was trying to make. If they get a message while removing that crap, well, that's just a freebie. It's a "karma" thing. What goes around comes around.
Their opinion would be the same...it becomes a vicious circle to see who can do the worst. I prefer to show maturity that is expected of our party and not get involved in defacing the opponents property. Though it would earn bonus points to have the creeps arrested for vandalism if you caught them.
