There is a close association between the nontheist community and the skeptic community in general, and let me tell you, any skeptical person should be incensed at the anti-vaccination movement. They are spreading dangerous -- sometimes fatal -- misinformation, sometimes even outright lies. Many worried parents are being taken in by this, and it's causing a drop in vaccination rates that, let me be perfectly explicit here, will result in dead babies. I hope I'm not being overly melodramatic; this is just the reality of the situation.
Anyway, she wants me to come so I can correct any misinformation that surfaces. I'm certainly no expert, I'm just a guy with a degree from the University of Google who is a little bit better at telling the bullshit from the non-bullshit than your average Oprah-watcher. I also have trouble watching my temper when I talk about the anti-vax movement, because it's ultimately a selfish and inhumane position. So we'll see... It may be disastrous!
