> Oh, my sweet, summer child.

I remember someone replied with that to a comment of mine. I find it hard to find words for it as a non-native speaker, as I don't have to express this often, but it's rather derogatory/denigrating/belittling, as if someone is speaking complete nonsense. At the same time, it's not an obvious personal / ad hominem statement, so it's unlikely to be moderated.

Or maybe I'm completely misunderstanding the attitude here.
