As an interesting aside, I recently (last night, actually) found out that my wife's best friend, who is pregnant at the moment, is an anti-vaxxer. My instinct is to come at her with a bunch of data and facts, but I'm aware that it is probably a losing strategy. One of the earliest interactions kleinbl00 and I had on Hubski was a discussion about the anti-vax movement, because his wife is a naturopath who deals with OB/GYN and therefore has lots of experience with these types. I'm looking for advice from anyone who's dealt with reeducating ignorant, scared, willfully intransigent, types. I'm a scientist, and I think I come off as condescending to some people, especially those who have strongly held but wrong ideas. So, KB and anyone else who's knowledgeable on this topic, hit me. What's the best approach? I assume fear is the primary motivator for being skeptical, no? But fear of what? How to allay those fears, etc?
