On the object-level topic of Said Achmiz, I have said all I care about, and I shall say no more. But there are deeper philosophical disagreements underlying the object level, which you correctly point to in your second-to-last paragraph. In fact, reading point number 2 in that paragraph reminded me of this classic and critical excerpt of Eliezer's writing in the Preface to the new Sequences:

I thought, and still do think, that there is an unfortunate problem wherein treating ideas courteously is processed by many people on some level as “Nothing bad will happen to me if I say I believe this; I won’t lose status if I say I believe in homeopathy,” and that derisive laughter by comedians can help people wake up from the dream.

I believe that saying someone's argument or belief is Obvious Nonsense and can be dismissed because it's already been conclusively addressed in a dozen posts in the Sequences, and using these exact words to say it,^[1] seems to me like an absolutely pro-social and frankly necessary part of maintaining epistemic hygiene in a truth-seeking community.

   As opposed to, as a hopefully-relevant example, the EA Forum college-campus-style "we are all friends and you are super smart and I will do anything to avoid offending you and I will acknowledge all your emotions as valid, while trying my hardest to find an angle from which our disagreement disappears instead of addressing any of your actual points"
