I read it as good-humoured incredulity, something like: "This comment is so intriguingly bizarre, I don't where to begin making sense of it – can anyone explain?"
Sounds like you read it as something like: "I am angry that I don't understand this comment and I demand others stop what they are doing and explain it to me immediately."
Either of us could be right, but it doesn't matter, and I'm happier!
