They are deliberate misrepresentations, but taken to such an extreme that I thought a single disclaimer would be sufficient to convince people that to nitpick at the list is to miss the point.

I did put thought into the misrepresentations. The first item in the list starts: "I want people to cut off my head". I wasn't exactly subtle.

I'm not apologizing (although given the reaction here I realize that it was a bad idea so I will refrain from making such lists in the future). I had to choose between giving a really good list about beliefs people here are likely to hold (would be too long and distracting) or a list that's humorous and laughably bad, but that would still touch upon many issues (ethics, cryonics, AI, friendly AI, time, quantum mechanics) to emphasize just how many opinions (mine at least) are influenced by the sequences and the community here.

The list is meant as a reflection on how crazy LessWrong seems to an outsider.
