Interestingly enough, The Interview never actually hurt the feelings of the North Korean people. In order to do that, they'd have to learn about it first. And there's nothing less likely to find its way into a closed society than a comedy about the assassination of that society's leader. But that's largely irrelevant: we don't live in a society that enforces "respect" at the expense of individual liberties.
There's a significant difference between being able to respectfully engage cultural differences and blindly accepting the abuses and atrocities. Particularly when we're talking about the sort of practices that make North Korea, well, North Korea (which have nothing to do with a Korean culture that dates back centuries and everything to do with one family's mad desire for absolute power).
