Fortunately (for the show), DS9 chenged later on the narrative away from that black & white Cardassia = evil, Bajor = good. I always imagined Kira, being a Cardassian, as brutal and convinced about doing the right thing as she's done as a Bajoran resistance fighter.Kirk kissing Uhura was probably more of a shitstorm than having a character announce they were a terrorist when their planet was basically occupied by nazis would be today. Obviously it depends on execution, but we're talking about Kira. She didn't exactly extol the virtues of murdering innocents. The show basically bludgeons you with how great the Federation's code of ethics is. Nobody would get mad, except those 10 random people on twitter and maybe some moron on Fox News.
