I haven't made up my mind. I tend to believe the second one more than the first. I don't really think he is lying as much as insane. I highly doubt that he is a time traveller.
I am also not going to discuss him any more because if he is lying, then this is his motivation. To see how many people he can get talking about him. I'm not going to join in. I'm just goin to think about it to myself.
I agree. The only way I would believe him is to be taken inside a time machine with him. Of course, even though his discussions have survived 3 years and are still talked about, I imagine he will be discussed a lot less in another 3 years. (That is, unless the US really does enter a civil war. Then, he might be talked about a great deal more.)
