I can think of a few small burgs right here in my neck of the woods where this sort of "protest" would immediately draw some very intense "scrutiny". They would find themselves the center of attention, "surrounded" by conservatives who were eager to "understand" what they are all about. They would be "questioned" very carefully about their attitudes and opinions so no one could mistake their message. We would want to understand their take on the symbolism and message content behind burning the flag or using foul language in public discourse. In return, we could "educate" them on our opinions of the same subject. We could offer "solutions" for their problems and "treatments" for their ailments. Heck, they would probably even earn "free transportation" on their return trip to the left coast from our always "friendly" and "helpful" law enforcement community (well at least as far as the county line that is).
It always puzzles me why these very devout and opinionated liberals never come to my county to convert us simple folks from our wayward path. Oh well.
I still say just one well placed little earthquake, along the right fault, and California is ALL RAD!
