Surely you can see the hypocrisy in calling someone "crazy" or a "group of nutters" when you yourself hold views not at all disimilar? To be honest, the date itself is relatively unimportant, I would say that anyone that believes in the Rapture and Judgement Day would fall into the "equally crazy" category, they just haven't assigned a date.
I wasn't calling him crazy due to the beliefs he may hold in regards to the world ending, but because he goes completely against what he claims to be following. It seems to have been given a lot of media attention probably just to discredit Christianity as a whole, but I don't think he could be any further away from Christianity if he tried.
