Their entire existance relies upon mythical beings. This makes them thirsty for proof that their so-called 'god' and other idotic characters actually exist/ed in some form or way. This leads them to searching for them in places like highway signs, muffins, warts, tumors, and even their own biological waste.
I mean, really... would any of you spend hours staring at an ugly stain behind a highway sign? Of course not. Why? Us Satanists have enough common sense to know that there are better ways to use our time, than seeking behind highway signs and under rocks for 'divine signs'.
I'm sure I've just repeated what many have said already. Still wanted to give my two cents.
Fate is a book,
Man is it's writer.
