My feeling is that while enjoyable and thought provoking, TNG is still a work of fiction, and as such favored entertainment and legibility within a 45 minute window over nuance or subtly. That meant there were clear distinctions between "good" and "bad" sides, and scenarios often felt like they were constructed backwards from an outcome/clever solution.
I think that in turn causes people to view the real world in the same way, except they are always the "good" side and solutions that require compromise and tradeoffs are seen as unacceptable failures.
Totally agree on the 45 minute window limitation though. That's why I've always liked DS9 where they took what could have been one episode about a culture and conflict and made it 7 seasons.

Homer is nothing like Star Trek and its story is not a moralizing adventure.
If you want to critique the stories and the storytelling of TNG or whatever else, please do so - there's plenty to get into. But "still a work of fiction" is not a critique worthy of anyone's time.
Fiction in the case of TNG is an excuse to spam aphorisms. The whole scifi setup is not the point of the stories.
