Well, as far as the libertarian party is concerned, Star Trek was anti-libertarian.
To an astronomical degree.
You never saw Kirk or Picard intimate with a child. That is part and parcel of the history of the libertarian political party, so yeah Star Trek has been deeply anti libertarian if you look at it in that light.
I remember an article on how the Federation is a fascist state.
Bashir’s parents faced a Star Fleet judge for their genetic enhancement of their son. That’s the equivalent of standing before a military judge instead of a civilian one.
Star Fleet captains are famous, as if they are the celebrities of their era. Civilian celebrities aren’t really known, though a few musicians are mentioned and scientists shown.
Star Fleet captains practically violate the Prime Directive five minutes after citing it, but rarely face consequences for it. A prime law for thee but not for me.
Star Fleet seems to manage interstellar communications, even for civilians. That’s like the Army or NSA controlling international phone calls, instead of just monitoring them.
Star Trek’s humans are utterly atheistic except for those few who fled Earth (Chakotay’s ancestors, who left earth to keep their culture).
Jake Sisko works for a Federation News Service, like Pravda.
In “Homefront”, you don’t see civilian police on Earth, all Starfleet.
If you have encountered any self identified Libertarians who believe sexually abusing a child is acceptable behavior then I’d suggest they have misidentified themselves. One’s individual liberty stops when its exercise deprives another of theirs. Children under law are not able to give consent to the kind of intimate relations you allude to and anyone who believes otherwise is simply a monster who should be locked away or worse. Not sure anyone has ever surveyed the political leanings of NAMBLA or the American Psychiatric Association membership but the chances are you will find most if not all of them vote Democrat.
That is a very brave thing to say.
Are you brave MrEdd?
