I have to think you don't actually believe what you're saying.

I basically agree. I had said:

Humans aren't "naturally" like that - at least only a small subset of memes convinces normal ones of the intellectual truth of the proposition "life has no meaning because/if you merely die at the end".

I think it is important to untangle belief and belief in belief here. timtyler is talking about his beliefs and so is sharing his beliefs about his beliefs, and I don't think he's likely lying.
