I don't really see the run-o'-the-mill thread stuff as debunking =) I offer viable, far more likely alternatives, or request evidence: people are free to counter-claim, or re-define their claim, or argue, or offer evidence. It just so happens that they usually do not or cannot. If I had an experience to pass on that I thought was valid, I would press the issue. As almost every claim that people make here is demonstrably... "flawed" in some way, I guess they were either (a) satisfied by the alternative explanation or (b) realised they weren't fooling anyone except themselves. Of course, they may also have been (c) eaten by the monster chasing them or (d) captured and killed by hunters while in their werewolf/vampire/demon form. But I'll go with (a) or (b) as vastly more probable.
