Anything that forces people to think twice before resorting to the laziest, least free form of 'free' speech that is the default knee-jerk Nazi comparison has to be a positive innovation. A properly-legislated version of Godwin's Law would only give more power to humanity's exercise of freedom of expression.
What would life be like in a prison camp? We can postulate about dirty, cramped conditions but few of us will ever experience anything remotely resembling such an ordeal. It is even hard to imagine. The only given is that we would live in hope of being liberated from our nightmare. We would expect to be rescued as quickly as humanly possible.
