It's a shame that these are so often the takeaways from a show that is at its core about a group of people with different skillsets and backgrounds working together with mutual trust and respect to further a common goal.
As a comparison, back the day I t liked Babylon 5 better. Tried watching it again and just couldn't the way I can always rewatch ST TNG, DS9 or even Voyager.
On the other hand there is the fact that Starfleet is the de-facto military junta, a morally fine one of course. Or moral high horse crap like the prime directive. The overall optimism is good so, and especially DS9 did a good job in showing the ambivalency that comes from ideals meeting real politics. E.g. the arc between Sisko and the Maquis, having Sisko side with, of all people, war criminal Dukat.
