It's tacit disapproval, but not quite strong enough that people will go off on a tangent about it in the comments (though they still do).
This kind of interpretation is why we can't have nice things. Everything you read these days has to beat you over the head with their point, or caveat everything in a sad and painful way. It's the death of joy and play in writing and reading. I'm glad people like Scott can write so boldly, even fully knowing, as I'm sure he does, that the joy and play will be read in the harshest light. And I mourn for all the joy and play I'll never read because people are rightfully afraid of being miscast and mischaracterized.
Give me an example, and I can probably find somewhere he's explicitly, unabashedly condemned it, and you probably can't find somewhere he's condoned it. Most of the places I've found myself in disagreement¹ with Scott Alexander, it's turned out that I was the one who hadn't thought through the moral implications of the thing I condoned.
