When things finally spiral out of control (in what way? take your pick) just watch how fast those "Obama/Biden" and "Coexist" bumper stickers get removed from every lib's car.
I can still tell if the car is a Subaru or a Hybrid (or full on electric) . The Cannabis sticker will still be there. The back will still be packed with crap and dog hair, and a cloud of SMUG will still surround them. And if you can get them talking they will reveal themselves -- they simply can't have a conversation without injecting their heartfelt and arrogant superiority and bragging about their fabulousness ( "I live next door to the VERY BEST Ice Cream store in the world. The Ice Cream you eat is okay, but you have to try this store, because it has the VERY, VERY BEST, no one makes it better, ice cream.. except for maybe that one place I visited before I climbed Mount Kilimanjaro and after that fabulous Trek that I took to Nepal..." BANG!)
And even if that doesn't work just ask them if they believe in Live and Let live, or to explain the idea that their rights end where yours begin, or just to explain why they believe something and how they came to that conclusion. Silence? BANG!
They won't be fooling anyone.
