Children comments to theirs, not childish commenters. For what it’s worth, I thought the same thing on first read before I realized another interpretation.
Sorry! You’re right. My bad assumption, I’m embarrassed. Apologies to parent @szvsw.
FWIW, I completely misinterpreted their comment too. I thought they were talking about actual young people and the intersection of innocence and ethics or something. Never would have connected it to "child comments."
