It has recently come to my attention that many politically incorrect jokes actually serve a useful social function—they remind people how NOT to do things. The big problem is the targeting of people who belong to a group which they cannot choose to leave. So instead of telling “moron”, or “blonde” or “Iowegian” jokes, let’s tell the same jokes about antivaxxers. Unlike members of the usually targeted groups, every single antivaxxer has joined willingly and can leave at any time he or she wishes!
