Dear Prudence,
One of my dearest friends has become a staunch anti-vaxxer. I've done my research from reputable sources and I firmly stand on the other side of the debate. Every conversation with her turns to the subject of the dangers of vaccines, genetically modified organisms, and processed foods. She is obsessed and brings it up at every opportunity. I read the articles she posts on Facebook and they make me ill. There is no research, it is all fear mongering, and this otherwise intelligent person eats it up! I want my friend back but I also feel like a jerk for thinking less of her for believing this stuff. How do I get past this?
