In Star Trek, nothing is explained, it’s all handwaved and is just there as backround to the stories. You said it with your own words “the setting” that’s not the story or the backround of the universe now is it? You contradict yourself in your own point. Just because there is spaceships doesn’t mean it’s scifi, please provide an actual source that supports this exact statement. No one should take you for your word, especially when there is now a posted source that contradicts your statements.
That’s why it’s fantasy. Yes advanced technology exists, but how did they get there from where we are? If you need to suspend belief, it becomes fantasy instead of sci fi
I like their description though, it is just space elves and Klingons.
It just sounds like you self publish and call your stuff whatever you think will sell. Why should we listen to you? There’s sources and credible authors who support here views. What are your credentials, if it’s self published, you’re nothing more than a troll.
