Idk the full context but I might call this a motte-and-bailey. If he was simply talking about "transcendence" in a general mystical sense then I would agree, that's subjective framing. But considering who it is, I suspect he's using this to defend more specific religious claims.

You're thinking about this all wrong, those are human constructs. The real dichotomy is between cars and giant robots

That's just his origin from The Killing Joke, and in that it's unclear if he made it up. His origin changes depending on the universe.

One thing that's consistent with most of his portrayals is that he's a talented showman, and he at least thinks of himself as funny.
