I myself wouldn't use LW meetups as venues for seduction. I would however guess that most of the people who act creepy on LW meetups do see them as venues for seduction. If you want to convince those people to change their behavior I think it makes sense to speak in a language that they are more likely to understand.

If you use the kind of language in which the main post of this discussion is posted, I think you are unlikely to reach the people who pose the problem. If my intended audience wouldn't be the people who pose the problem but the people who are fluent in deconstrutivist language I would speak differently.
