(The Pentagon was just the quickest example I could think of to illustrate my point.)

Re: "...how much time and trouble you and I have actually gone to in looking up stuff to support our opinions. "

It is obvious that, in this day and age, with all the myriad shows, sites and articles bombarding us with claims & counter claims, most of us do not have the resources OR time to investigate the details personally. The trick is to develop our understanding of who IS likely to have the most 'neutral' data and information.
   Places like "Snopes" exist to sort out some of the 'old wives tales' from truth, and find answers, not rumors. Google, and related places, can find ALL the opinions...from the most extreme silliness to details by real experts...and everything in between. It is ok...even GOOD....to read a selection of all of them, to get a feel for the directions the issue is going - and then to investigate the more....ummmm....'astounding' assertions & theories from other viewpoints. Often, like the Pentagon camera, the answer if relatively simple. Other times, as in some reports of UFOs, it ain't so easy, and needs a LOT more investigation.

   I think there are some basic differences in people...some can't abide not having **answers**, and will adopt 'A' until 'B' seems better...others, like me, are content to just not KNOW some things, and will be highly suspicious of pat answers and claims that seem premature.

and so it goes.........
