"One of the things that's always puzzled me about the anti-vax movement is why people are motivated to rail against something with so much supportive evidence. Sure, there are legions of misinformed parents who think they're helping society by decrying the vaccination conspiracy, and there are certainly those that have experienced personal loss due to the very, very, rare negative side effects of vaccination. But Chiropractor Dr. Chad Rohlfsen illustrates in abundance what I think might be the primary motive for anti-vaccine rhetoric, and that is pure, simple, banal greed."
