Well, right. What I'm having trouble deciding is whether I believe that's what he meant.

Or, rather, whether that's what he meant to express; I don't believe he actually believes nobody other than RationalWiki is clueless. Roughly speaking, I would have taken it to be a subtle way of expressing that RationalWiki is so clueless nobody else deserves the label.

I was initially trying to decide because it was relevant to how (and whether) I wanted to reply to the comment. Taken one way, I would have expressed appreciation for the subtle humor; taken another, I would either have corrected the typo or let it go, more likely the latter.

I ultimately resolved the dilemma by going meta. I no longer need to decide, and have therefore stopped trying.

(Is it just me, or am I beginning to sound like Clippy?)
