I’m always a fan of the “Pro-Choice” / “Anti-War” combo...
Even better was the one with “WAR KILLS” next to the “Pro-Choice” sticker...
As the quote goes - “For those who understand, no explanation is necessary. For those who do not understand, no explanation is possible.”
Yeah, those are always good for a WTF?! moment. There's a woman I see in morning traffic every week that has a similar combo: "It's a Child, Not a Choice!", right next to "Vote Democratic". There's so much cognitive dissonance in that car, it interferes with my radio reception.
