I'm serious about the propositional content and implied emotional attitude towards it, but not about my means of expressing it or choosing to do so in the first place. I thought it sincerely, and assumed you would assume that I thought it sincerely, and so I posted it because verbalizing socially inappropriate thoughts that everyone-knows-one-is-thinking-anyway is funny, and because we've had friendly enough interactions in the past (whilst acknowledging mutual indexical evil) that I didn't think you would infer that it constituted a "real" social attack.

Does that make sense? (It's also about the limit in terms of how many orders of intentionality I can work with, if you want to run circles around me in our next/this interaction.)
