The problem I've noticed with your idea of speculative theories is that members seem to be either a) unwilling to research the topic and add to it, causing the thread to die, or get buried or b) will completely sidetrack a thread over one individual fact, in sense, killing the theory and turning it into an argument over a fact.
It also seems that people want every single fact laid out in front of them. Every link, every source, every theory and facts that lead to that
theory, every person's name, every proof of documents, every.. everything.. People seem to be unwilling to research a topic brought up (true or not)
on their own. They expect a person presenting a theory to literally prove it instead of theorizing on something.
I've only presented a few theories on ATS.. most of the time I was stoned out of my mind when I came up with these wicked conclusions.. and most of
the time I was proven wrong (for obvious reasons). But one thing I did notice was the tone presented when a theory is put out on the board for
discussion. If it's not fact, it's not worth talking about.
Asking someone to theorize, and in the same breath prove their theory is real and conclusive is to me an oxymoron. We should view a theory, correct
any errorenous facts, and try to add to it.. not shoot it down into the "debunked" bin.
The urge to prove wrong and debunk things on ATS probably adds to this. I save my debunking for situations, stories, and claims.. not theories.
