What it is, is a classic logical fallacy, one big argument from ignorance. "This stuff is like this, well how else can you explain it!? Therefore, it must be spirits!" "Lightning bolts in the sky!? That guy said it was Zeus, and well, I don't have a better explanation, so it must be Zeus!" That's not thinking outside the box, it's certainly not looking for any possibilities, it's not even thinking within reason - It is just completely asinine... It is not unfair to have a bias towards truth, not unfair to have a bias towards things that are scientifically demonstrable, nor is it unfair to discriminate against bat-shit crazy ideas that happen to be popular with somebody.
