In my life, I've known parents who've tried to teach their kids lessons and were horrified to see how their children got them completely backwards. Like maybe their son tells them he did something wrong and he gets punished, and then they're disheartened to hear that the kid believes he can't come to his parents with anything without getting in trouble. In trying to teach him to be honest, they taught him to lie.
Authors of fiction are nowhere near as responsible for the morality of their readers as parents are for their kids, but I can't help but think someone like Gene Roddenberry would be equally horrified and disappointed to see how Bob got the lessons Star Trek was supposed to teach exactly backwards in the same way.
Roddenberry presented a future where humanity had finally overcome its differences and biases and ushered in a beautiful utopia, where everyone was equal and happy even though they were still different. Cultures and races still existed, but they lived in harmony. What Bob took away from it is that "inferior" people who didn't think like the good guys in Star Trek were keeping this from happening, and that by systemically erasing or even killing them we'd finally make progress towards it.
Roddenberry envisioned a world where technological advances had finally reached their apex, and things like poverty and sickness were now complete non-issues because you could have any material object you wanted in an instance and there was no disease. Machines had advanced to and made people's lives better. The lesson Bob took away from that is we should actively make people's lives worse to make machines better, and that by disenfranchising and punishing humans for the sake of scientific progress the "good people" can get everything they ever wanted.
Replicators creating an endless amount of material possessions was meant to show that now they no longer have any value but necessity, and that humans were free to pursue higher goals without having to worry about where their next meal would come from. Bob learned to desperately covet the technology on the show and become angry that he didn't have a replicator or a robot body yet, blaming it on republicans.
Star Trek was a show about characters who always fought to do the right thing and hoped it would lead to a better tomorrow. Bob decided that instead, people do and support the *wrong* things because of a dogmatic belief that eventually they'll result in a greater good.
Roddenberry created an idealistic, optimistic and hopeful vision of a better world and Bob decided to it as the "money shot" in his nihilistic eugenics-fueled fascist power jerkoff fantasies. After all the dirty dumb farmers and mechanics are slaughtered and turned into canned meat, Bob can jizz to the thought of hoverboards and robot bodies.
