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?
Star Trek is nerd culture. Nerd culture is predominantly white cishet guys. White cishet guys who feel excluded from the rest of society or face issues growing up (which usually leads to them being nerds) tend to be radicalized by far-right talking points as a replacement for an identity.
Not all of them of course, but a lot of them. That's the reason. Star Trek is different than other fandoms in that it historically has always been a lot more diverse than other fandoms. If you think the Star Trek fandom at large is bad, check out others. Way worse.
Yeah Star Wars fandom is much worse, at least in my experience
