Excellent post,
Spacedad, and welcome to BAUT. In a way you are "preaching to the choir" here, but people cannot be reminded too much that debunking all these falsehoods, urban legends, myths, etc. need to be dealt with on a daily basis that reaches people on a mass level...TV.
Personally, what I do in my little niche of the world is use email. I work with regular folk, some of who are fascinated by ghosts and such, and am barraged with emails that are falsehoods and old urban legends. I've taken to hitting "reply all" and using Snopes to counter some of the pervasive falsehoods that circulate; those who do not BCC (blind copy) give me the satisfaction of knowing that my responses are going back to many people. I am becoming a bit of a "wet rag" spoiling their fun, but what I do is turn around and send out real photos, say of that hilarious penguin hopping into the water, or something of interest that is real, enjoyable or medically useful. Some people say, "Thank you, so glad I didn't buy that star," so it's just my small way of doing what I can, but it's never enough. Good shows like Mythbusters, et al, are great, but it's still not enough. I work with two people who don't have cable and don't read books, and so don't have exposure to Mythbusters and the like.
