Again, while I respect that that is your view of sincerity, I don't agree, and I'm not talking about lying, which is obviously inappropriate. Framing is not the same as lying (though taken to an extreme it becomes a lie of omission). There's also just a misunderstanding of what is being asked by questions like "what's your biggest weakness?" Language can be ambiguous, just because a very literal and extreme interpretation of a question exists doesn't mean that is what is being asked.
I don't think we're going to bridge this gap but I also don't think that's really necessary. People have different values and it is what it is.
