It's hard to explain sarcasm. Trust me. It's sarcasm. He's saying that conservatives must be wrong that the court doesn't defend life because they defend this wretched murdering juvenile. Nudge, nudge, wink, wink. In other words, the court doesn't really defend life. Are you getting it yet?
He's being sarcastic, that's how--ironic--saying "yes" when you mean "no". It's obvious to everyone else here.
