> My read of the article is that the author ascribes negative traits without judgement and just as easily as positive ones
I don't think this is true at all? The 'negative traits' she assigns to people are things like desperation, self-hatred, 'hating the world (or having a very narrow understanding of it)', 'thinking they are better than everyone'. It's hard to call those categorizations anything but judgemental. She even goes as far as to say she has a 'favorite kind of person' by these categorizations. That she ascribes them as easily positive ones is meaningless. It's the ascribing that is the problem.
My take away is that the article is a small list of things that most people know (i.e. it's easy to tell if someone is actually interested in something or not) paired with a series of ways to judge someone based on some extremely surface-level traits, which slowly veers into a sort of prescriptive take on which combination of those traits makes a person identifiably good. It has a feel-good tone, but I found the article difficult to get through because it put me off so much.
> Heck, as I see it, big part of empathizing with someone is recognizing how all their conditions and traits are natural and operate similarly inside ourselves to one degree or another.
See, to me applying the 'insights' outlined in the article seems like the opposite of empathizing. It's couched in gentle phrasing, but it essentially boils down to "here's how you put someone into a box by looking at them."
