Here's a few examples:
The Popcast (recently made a video warning of the "dangers" of the Barbie movie because it's feminist. Now Im going to go see it lol), Midnights Edge (general right wing conspiracy theories regarding media, occasional delving into new age crank too), Nerdrotic (thinks Hollywood is engineering a communist Red Guards plot to kill conservatives), The Critical Drinker (typical edgelord anti feminist), Dave Cullen (extreme anti feminist who believes in all the QAnon, Agenda 21 conspiracy theories).
And it goes on and on. I know there's popular left wing and liberal reviewers too, but for whatever reason so many of the ones I run into are far right. Is there some sort of draw for conservatives to geekdom or is something else going on?
Youtube systematically encourages rightwing content both because rich people rely on braindead conservatism to retain their strangehold on society and also because rightwing content is junkfood optimized to cause strong reactions in people and manipulate vulnerable, afraid people.
I also think it is important to point out that if you step back from Star Trek and squint, you can see it as a scifi submarine war drama about the glory of serving your country in the navy. Nevermind that starfleet is much more than a military and comparing it to a present day military is a huge stretch, that the federation is a leftist mostly functional utopia, that Star Trek directly speaks to the dangers of blind patriotism and militarism.... Conservatives don't let the details of reality get in the way of the narratives they tell about the world.
Renegade Cut did a really good video that I think does a pretty good job of answering your question https://www.youtube.com/watch?v=69Tm5KxkM8A&list=PLbNseMNQjpNuh2RfoyBHTAad48PN-MZa5&index=5
Damn, couldn't have put it better myself.
