I'm glad it is a parody!

But the clue was that the dead people weren't really dead! Nearly dead---yes, but not quite, so asking questions of a living person about what it is like to be dead is rather foolish. Because they are not dead. If they were they would not be speaking because they are dead.

When we are an X-person we have no more input into philosophical debate, because we are dead. Unless we believe the dead are not in fact dead but are frolicking somewhere, with varying degrees of comfort.

It's all to do with the belief, -again.
