Somehow I’m on the mail list of a person who does not believe in vaccination. He sends me all kinds of scientifically illiterate tripe about the dangers of that well-proven science. Of course, his messages are followed by dozens of responses from “friends” near and far. A few disagree with him, but most add more nonsense. I rarely comment, but the other day I appended: “Someone said ‘Love your neighbor.’ You should try it.”
