I agree. I find it funny that you lead your list of examples with "cached thoughts", because that exactly what these are. Not that that's a bad thing.

If that's the case though, maybe we need to be proactive in preventing them from becoming cached thoughts of the bad kind. Eliezer's posts serve as a good introduction, but I don't think they are the ideal reference. Maybe a rationalist dictionary would do the trick. I envision something like urban dictionary where multiple definition/explanations can be submitted and voted on.
