I do see some hypocrisy in certain areas;
When other cultures, like the Bajorans are being conquered, the Federation because of the PD, will willfully ignore it.
When the Federation's existence is threatened, they will ask, even beg for help from other powers.
If they don't get it, they get angry and resort to desperate measures.
Billions of Federation citizens are living in luxury because Starfleet secretly tricked the Romulans into war.
Maybe things like that are unavoidable in order to perserve paradise.
Maybe this a backlash against TNG's preachiness- at that time, it was 'how different we are from those savage 20th century people'
Then DS9 and Voyager and even Enterprise pretty much challenged that idea.....
