Earlier quoted context omitted.
What does it mean to say "we must respect the law"? Banksy demonstrates that this is not true. You only need to avoid law enforcement. It seems to me, of course I have no way of knowing, but it SEEMS to me that you are NOT EVEN AWARE that you're not making arguments.
We don't have to treat each other as humans, either, by that logic.
Nor did you. You just appeal to some popular notion that everyone already agrees with ("treat humans like humans"). Then you suggest this is the same as the other thing, again giving no reason.
Maybe you really can give reason to someone, who abuses people, not to do it. To treat humans as humans. But you would have to delude yourself to think you already did it here.
