It's amazing to me how angry people get at people who choose not to vaccinate.
Throughout history there are countless examples of medicine and medical practices that were deemed safe that turned out not to be.
And the published reaction rate for vaccines is not 0.
So, while completely rejecting conspiracy theories or vaccines as a cause of autism or ADHD, I don't think it's fair to demonize people who choose not to put something into their body that they don't fully understand or trust.
Just calling them names or stupid isn't going to help. A little more empathy and less anger might actually help adoption.
But the last time I checked aggressively guilt tripping someone into a health decision usually creates more resistance than adoption.
