It wasn't an academic paper, it was an internal memo posted to a discussion forum. Even then, it was well structured, moderating in its commentary, and peppered with links to support its arguments.

This sort of criticism seems like motivated reasoning to me, and only comes out when current progressive dogmas are being challenged. When HN applies a scalpel the way you describe to the opposite viewpoint, often supported only with anecdotes, out come the complaints how people's lived experiences are being ignored, how it's proof of a cultural problem, and so on. Not to mention the flagging. It's rigor for thee and not for me.

The media and Google are the echo chamber when it comes to this topic, that's been demonstrated plenty. If they were capable of intellectually reasoning about it, they wouldn't be lumping together reasonable criticism with that of the fringe in the first place.
