^As I've tried to get across, there are human beings who are just as severely learning-disabled as B-4, but if you asked those questions about them, or alleged that they have no human rights because they don't reach some arbitrary threshold of smartness, it would be horrific.
B-4 clearly had the capacity to ask questions, as a child would. He just wasn't good at retaining or understanding the answers. He's learning-disabled, not mindless.
As I said that's an interesting view but if B-4 was the way he was on purpose then he isn't exactly disabled in fact he's functioning properly. You can't be disabled if there's nothing to disable if that makes sense.
