I get spergy levels of angry when speaking of anything that has the underlying message can be summed up as, "If you fight against genocidal maniacs, killing them is the same as them having committed genocide" or something similar. Or a story that has the message of "don't interfere, even in situations of genocide" because of some bullshit about culture justifying anything or a group needing to undergo the trials/lessons/etc. on their own as if it's some test for them.
It betrays a complete and utter lack of knowledge of what happens during a genocide and how cruel, severe, and egregious the crimes involved are. To compare killing innocent people to preventing monsters from harming others, or to act as if cultural belief excuses it, or that it's a test of some kind, is so asinine that I get the impression those authors know nothing whatsoever about history. They see the numbers and know the definitions, but they cannot put a face to it or a story.
That's incidentally why I think the original Star Wars trilogy is far more humanist than later Star Trek, in the sense of caring about universal rights. The Prime Directive is bullshit.
I'm not usually one to go on about underlying messages in stories, except when they're fucking hilarious in their unintentional meaning. But then that topic rears its head and pisses me off.
