Lurking DUmmies, I have read your bullshit about bumper stickers for nearly 15 years, and it's time someone sat you down and explained something to you:
NO ONE GIVES A FLYING SACK OF **** ABOUT YOUR BUMPER STICKERS.
If anyone is giving you stink eye, it's because you're an asshole, a situation that prevailed before you placed your magical sticker, and which will prevail long after your car is repossessed or hidden by you in an insurance scam.
If anyone is whispering about you, again, it's because you're an asshole.
Once you understand how completely insignificant you are, and how rarely anyone thinks about you, you'll be much better off.
