incentives: one should think very carefully before writing any comment that sounds like "this post really ought not to have been written".

While I don't necessarily hold that opinion of this particular post, it's a defensible position. I think that posts that use relatively complicated math where simple English would suffice substantially and negatively affect the quality of discourse. If someone has a OK point to make, it is arguably better that they not make it at all than that they make it in a convoluted manner, because that suggests to other people that it's OK to make such posts. It's certainly better that they start it out in the discussion section so that it turns into a more comprehensible post on the main page. Of course, the more original or interesting their actual idea, the more the benefits outweigh the costs.

Your different thinking styles criticism is absolutely on point though, I admit, assuming it actually applies.
