I watched the entire video, but I timestamped the link to where I believe it matters most for any comrade that ever liked Star Trek, liberal idealistic and quasi-militaristic flaws and all, and would like to see a succinct and thorough summary of what they might have already felt, may have already inductively collected for themselves, but got it drowned out by "well the TNG gang got together by the end of Picard Season 3 so just enjoy it like a popcorn movie, 4/5" or even worse brainworms like "section 31 is based and it's just cold hard reality that such an agency would have to exist for the Federation to exist, just like in based Deep Space 9 which was totally about wars and genocidal biowarfare plots and how cool and necessary they are."
The Trek fandom site in the Lemmyverse is loaded with insufferable liberal/libertarian 
and a fair amount of Thermian Arguments that justify anything that was presented on screen as not only good, but necessary if they were done by protagonist characters, and not just the flaws, weaknesses, and (for lack of a better term) sins of characters that weren't intended to be infallible, let alone blindly emulated, no matter how cool it was when Sisko punched Q or whatever.
TL;DR: I hope comrades find value in this concluding section of a much larger video, or maybe even watch the whole thing, which I also think is worthwhile. Also, I fucking despise Section 31 apologists because they make the Lemmyverse's Trek site unbearable for me. If Kurtzman gets his way (especially with that Section 31 series he keeps jerking off about), Trek will become increasingly murderfucky gory edgy black ops obsessed bootlicking schlock with a vague and redundant nostalgia flavor.
Yeah, its lazy writing. At least in Deep Space 9, you get the sense that while Section 31 has enough connections to keep itself hidden, it wasn't all powerful. If I were gonna pick up the plot threads, I'd have it be what it was first stated to be: a small group of essentially vigilantes, high on their own mythology and exploiting the gaps and shadows of a huge organization like the federation.
I think in some ways, Star Trek let liberals indulge in American Exceptionalism. Like, here's all the values we purport to hold, being evangelized by a good democratic federal government and its space-navy! Yes, they're socialist; but its because of replicators! Don't worry about it! Obviously, this varied across episodes and writers. Some might be more explicitly socialist, some might have a little more yankee-brainworms. But New Trek feels like its all in on the American Exceptionalism. So now Section 31 is just Federation CIA and they do "critical work" whatever that means
