Ok, imagine this scenario. Aliens from space land in your backyard. They just happen to speak perfect English, and they want to chat with you about current events here on Earth. In the course of your discussions you explain to them that the birth of a "red calf" in Israel is a sign of the end of the world, and that you and many other people are taking serious steps to prepare yourselves for the end of the world because of the birth of this calf.
You notice the aliens looking at each other with strange looks on their faces. They soon wrap up the conversation and bid you goodbye. As they are walking up the ramp to their ship you notice them checking a box next to the name "Earth" on a list. The box is marked "Hopelessly Insane".
