I suspect if I were LW-high-status, I could politely point out that while we've both argued from assertions, one of us has expanded on their assertion, and one of us has not.

What is it about being low status that makes you think you are better served by making the claim passively aggressively rather than politely? Politeness usually more important when status is lacking, not less. Or do you consider this style to be even more polite than, well, pointing out politely?

As it happens I have expanded rather a lot in my original message. I chose not to expand further in response to either you or bogus because I didn't see benefit to such engagement.

I take from your vehemence that your disagreement is more fundamental though.

The thing in the OP is bad. Replying to public comments isn't. That is all.
