Excellent critique. You nailed it.

Did you read the comments, which get a bit scary? (I thought by now someone would have said, par for the course for WaPo subscribers.)

I just now took a look. They seem all over the board, and it could be that the weirdest ones were edited out by now.

At least some of them acknowledge that there is an actual moral issue here concerning how to keep vulnerable children from being harmed. Pseudo-scientific speculation (even if grant-funded by FedGov at household-name universities) does not address that.
