Hey, thanks for all the replies.
I've been having major trouble getting back on here, getting some kind of "database error" over the past few login attempts, so sorry I haven't kept up.
Regarding the YouTube thread, I was pretty amused when the guy kept getting asked the same question over and over again, and he'd go further and further off the deep end with cursing, homoerotic slurs, and all sorts of weird stuff. He kept demanding that all the "Apollo fools" produce "one piece of evidence" that supported their claim, and one of them came back with links to the Apollo Lunar Surface Journal, Clavius, The Lunar and Planetary Institute, Phil Plait's site, the Project Apollo Archive, Bob Braeunig's site, this forum, and two or three more. Then when he finally got obscenely nasty and foul-mouthed, I sort of lost interest. I went to copy the link as someone requested, and accidentally closed the tab, and now I can't find it again!
I tried to go through my history to find the link but for some reason it's not there. I went back over a month and there are no YouTube visits at all in my history.
So, unless I happen to run across it again...
Bringing my original question back up again, why do people do this? Why do they sit there and keep screaming as loudly as they can that the whole thing was faked, and nothing will ever change their minds about it? How can anyone possibly be that intransigent in today's world?
