Not really, in LoTr, they have a magical sword that shines around orcs, another one that can stop a ghost sword, and there are being with biological powers beyond the grasp of our understanding.

I think you are confusing setting with genre. By your logic the star wars and star trek porn parodies are also sci-fi and not porn.

Sci-fi is only sci-fi if science plays an integral role in the story, eg. Expanse, Stargate (shows), Star trek. But these are all arguably in space, so I get your confusion, that’s the setting, shows like Black Mirror and For all mankind are also sci-fi and those are present day things.

Well actually For all mankind plays out in an alternate past where the space race continues (though I guess this is also technically in space).

Black mirror explores humanity through the lense of abusing technological/scientific inventions.

So those are science based fictions, sci-fi.

Star Wars is space fantasy, arguably if we live in an alternate universe and the original trilogy is released in the late 2000s and 2010s they could be dubbed as YA.
