First, when I say "OP", I generally mean the blog or video poster, not the person who posted to Lemmy. I know, it's utterly incorrect, but I don't have a better term. Publisher? Author? Blogger? Vlogger? Anyway, I don't assume the poster made the content, or even necessarily agrees with the content (although, people rarely post things they think are BS), so I apologize. It's a bad habit I'll change when I find better terminology.

Second, as you quoted the vlogger(?), Star Trek paints an unrealistic picture" is an unambiguous statement about their opinion, and which I think warrants my evaluation. Calling a sci fi series about far future politics "unrealistic" is an admission that one doesn't believe politics can change. More so, it exposes that one believed politics has never changed. It says, "what we have now its the only way it can be," which I believe is a good indication of pessimism.

I hope that clarifies and defuses any implied or perceived slight.
