These people don't want a debate. You'll notice that the person (or persons, I'm not sure which post you are referring to) did not stick around to discuss their ideas or defend their conclusions. They simply posted, then ran away like frightened rodents.

This website has been accused multiple times of being funded by NASA, the NSA, the Illuminati, George Bush (?), Barack Obama (?!) and the reptilian aliens (!!!).

Just to be clear, we're not paid to do this by anybody. The domain fees and hosting fees are minimal and are paid for by me, out of my own pocket. By the time 2013 rolls around I will have spent about $250 or $300 in fees to run this website.

Why would I do that?

My motivation is simple: Every time I think about stepping back from this debate, about letting someone else do it, I think about the kid (there's been more than one now, but this was my first experience with it) who came up to me after an astronomy presentation in 2007 with tears welling up in his eyes, because he was terrified that the world would end in 2012. He'd heard it from a classmate, who had heard it from an older sibling, who had seen it on YouTube.

I think that initially I was a lot like some people who happen across this debate and don't believe that it is serious. "How could anybody actually believe this?" was my first reaction. So, please believe me, I understand your anxiety. I also understand your frustration and anger with those who spread this hoax.

I don't know about all of the other posters or site members, but I feel that their motivations are probably similar.

I will not step back from confronting this hoax. Please feel free to come back and ask questions as many times as it takes for you to feel better. We will answer you as best we can, and as often as you ask.

Jim has a good point. 2012 believers are welcome to come and debate here. They claim that this website is hiding something or denying some event or other which they think will take place in 2012. Have a read through some of these debates. You will find that the 2012 believers are politely asked to provide some evidence for their claims and they either change the subject or become abusive. Of evidence, there is never any sign. Eventually, they retire with their tail between their legs.
As I've said before, their contributions are worth leaving in place for all to see because they demonstrate better than anything the complete lack of substance in the doomsday claims.

I'll give the poster the benefit of the doubt, and assume that he or she isn't cruel; just scared out of their senses by all the lunatics and liars out there.

Did you ask the "poster" which websites he recommends for finding out "the truth"? It might be interesting to see whether those sites allow debunkers to debate as much as 2012 proponents are allowed to debate here. That might give you a good clue as to who's hiding the truth.

I just read a post by some idiot saying that the world will end and that this website is hiding the truth or whatever. why would someone be so cruel as to do that. That sorta thing scares the hell out of me, i suffer with anxiety. wish i hadn't read it now !!!!!

I had calmed down about the whole 2012 thing untill today!! Someone told me that the people who predicted 2012 also predicted other things like september 11th!! apparently there was some photo of two buildings with a stick going through them looking like a plane or something.(representing the twin towers) I am really freaked out :(
