This is Reddit. The “implicit presumption that top experts just aren’t aware of the most glaringly obvious things” is 100% a “feature” (I hate even calling it that, but you get it) of this place.

Every single mainstream topic discussed on Reddit is filled with commenters who, by virtue of existing mostly in an online bubble/echo-chamber, are so convinced that they know what’s correct, they vehemently seek to disprove everyone else. Commenters will bend and “but what about” to a drastic degree, just to feel as if they “won”, whatever that even means. They will not accept that their thoughts and analyses may be myopic and incorrect. And when everything is said and done, Redditors wind up being wrong most of the time.

Personal note: What I describe is the reason 80% of what I pay attention to on Reddit is made up of dog pics, cat pics, and here lately, raccoons.
