See, here's what happens. You ignore them and they go away. We have a half dozen or so religious crackpots (yes, I don't think they're completely sane) who come to our campus and try to provoke and debate college students. They multiply in the nice weather, because people pay attention to them and stand in big crowds listening to their rants and diatribes. When it's cold or windy out, no one wants to hang around and pay attention to them. They yell into the winds for a while, then they disappear.
