Re:So we can't call anyone stupid anymore (Score 1)

Yes, one would be stupid for walking around in a lion's exhibit. Lions are predators. They're not capable of any other choice.

Humans are self aware and have choices. While we must recognize that many humans make the choice to be predators that doesn't mean that we should expect or accept that choice. The Japan example shows that humans actually can be better to each other. It shows that an expectation that things should be different is not unrealistic.

That isn't to say that I don't think people should be careful but the expectation that they shouldn't have to be isn't unreasonable.
