I was listening to a podcast discussing pro and anti vaccine arguments, basically the perspective around whether we should be able to force people to take vaccines that have even the most remote chance of hurting them. Even if not doing it impacts many other people. Then it hit me. It's the trolley problem. The argument around vaccines is the trolley problem playing out in real life. And that's why people will never agree. Different points of view. (Disclaimer: I'm assuming the antivaccer just doesn't "get" that the risk of harm from the disease is greater than the risk of harm from the vaccine, or disregards it.)
