That makes sense. I'd only add that the readers will probably form a range of opinions, not all have one opinion, as you appear to suggest.

But anyone's attention is limited, and it naturally goes to what they're unfamiliar with. When you, as one in the know, read that article, many of the rationalist talking points were familiar to you and didn't register much. A reader new to this would use up much of his/her attention on those parts, and less on mundane things like body shapes.
