I'll sometimes engage in the debate just for the sheer fun of watching them flounder when presented with facts. My godmother is your typical Denver liberal -- thinks she's moderate and the rest of us are hard core conservative. She also makes much of the fact that she has Hawaiian ancestry and majored in History so one Christmas when she was spouting off about the NRA and the need for gun control, I casually mentioned that as a devoted student of history, she surely realized gun control came to Hawaii when the haoles overthrew Queen Liliuokalani and wanted to ensure the Hawaiians couldn't take the government back. She got real quiet when she realized it was true and she didn't have a counter argument.
