"It really is as simple as I've listed above. You have to actually chose not to believe it based on... um... lack of sufficient evidence?"I don't think so.
Besides faith, there are a couple of ways you can come to believe in something. One way is to witness something or have something demonstrated to you. In that case there's no choosing to believe - what is, is what is (depending on your definition of is

). Another is having someone tell you something. In that case you must make a choice to believe it (based on the likelihood, the credibility of the source, etc.).
When you apply the above to your list and Iraq's involvement in the WTC attack, the only people making choices here are the people who want to believe that this connection exists. Some people have asked you to believe it and you chose to do so. Me? I'll believe it when I see it.
It's funny to me that we're constantly given these scraps of information... such as Hussein paying Palestinian suicide bombers... and finally that we must be going out of our way if we don't believe in Iraq's involvement. Nevermind that the hyjackers weren't Palestinian suicide bombers. Nevermind that Hussein rolled this thing out some 8 months after the WTC attack. To be frank, I think I'm being quite charitable with you over this Iraq/WTC business.
It's always the same thing though... Like I'm supposed to ignore the peices that don't fit and make these huge leaps of faith in the construction of a theory (because ladies and gentlemen, at this point that is all it is), or else I'm just being... anti-.... a pain in the arse... *choosing* not to believe. Deth to Amreeka.
You seem to be saying that in the Deja world of jurisprudence one needs only to come up with a theory, bolster it with unrelated events, and call it fact until proven otherwise; as the burden of proof now lies with those who'd dare not accept the charges outright. Futher, to not accept the charges is to be playing dumb. Not a whole lot of wiggle room, is there?
All that being said, why in the world would I or anyone actually go out of my way not to believe something? It doesn't make sense to me. If somethings there, if it's real - show me, I'll believe.... Why wouldn't I?
