There’s little depth to your thinking here. You can’t be right or wrong about abstract concepts that can be analyzed from different angles. Yes, a chain is only as strong as its weakest link, but the point of such rhetoric is always to offer an alternative, higher vision and forge the weak links more strongly. Nobody would read the Bible if the only point was that people suck; you need to have the redemption aspect too, the idea that it’s always possible to strive for a better self. So give this guy a break. He’s not even President yet and you’re already throwing him under the bus.
