Sacred Haven of Debauchery

What does this have to do with Blacky's intentions? The meaning lies in your perception; I don't care what he writes or will write. He will eventually learn to express himself clearly, but you are wasting time and energy trying to convince April snow that it's time to melt. You're flogging the sea. But that's not important; it would be your business if you didn't resort to categorical statements, presenting your subjective viewpoint as an absolute truth.

Morni, there's no need to adopt the pose of a detached "objective" observer and criticize those who criticize Blacky; you're just playing with words, which is hardly an objective position, and the situation where "everyone is covered in... the story, and I'm in the middle wearing a white suit" only exists in Petrenko's jokes.

If I understand correctly, he's trying to say that spending time and effort explaining to a baby that it's wrong to poop in their pants is pointless. Right?

No, the situation is different: the baby crawls into a group of adults wearing soiled diapers and asks why everyone is frowning. Morni is also frowning, but pretends nothing is happening and accuses everyone else of trying to send the baby back to the nursery. That's how I see it.
