Gracias, Senor Hummus,
Like most of us, I strongly suspect, I've collected my own version of definitive answers and links. And simply cut & paste. That's a big time saver.
The folks here have wised up to Bill's routine in relatively short order. I've had an almost 2 year head start on his shenanigans.
Bill is a "special" character. As such, he deserves, IMO, "special" attention.
Tom
No problem, sir. Anytime.
And yes, I think we all have our own little compendium of links to lean on. Heck, mine's so large, I've got 2 levels of subfolders just to keep 'em straight. There are times I've wished I had a bookmarks search feature

. But, I've found that I lean on
Gravy's site,
Mike's, and the search function here the most; Gravy's, while only being a small amount of the information that's out there, still stands as one of the most encyclopedic. And Mike W's has some of the most straightforward explanations around.
The shame of it is that both of them do little more than link publicly available information. The more I use their sites as gateways to accurate information about 9/11, the more I realize just how pathetic 9/11 conspiracy peddlers are about their material; the rebuttals to their distortions and mistruths are so publicly and readily available that it has convinced me that you actually need to purposely turn a blind eye to truth in order to believe in the 9/11 conspiracy fantasy. It's one thing to be taken in on a minute, isolated point and think there's something legitimate there; as I've said before, the thing that captured me was being unable to explain the "molten steel" issue properly, despite my degree in chemistry. Individual elements can have compelling albeit misleading truther explanations to them. But it's an entirely separate thing to continue to see rebuttal after rebuttal and
still think there's an element of accuracy or truth to the so-called "Truth" movement. I saw the work they put into distortion after just one, single topic; it blows my mind to see others continually get the truth thrown, spoon fed, translated, diagrammed, and hurled at them over and over and still hold their beliefs in the fictional conspiracy. That sort of mentality rises to the level of pathology.
Anyway, you're welcome. And as a slight derail: Maybe we ought to have a "bookmarks sharing" thread at some point. That might be interesting. I'm going to ponder that for a bit here...
