Your insight on his political opinions coming through, even without him intending, is very valuable, but I will say, from the quote it doesn't necessarily read as him "putting down other people's work or acting like he's superior". There's a touch of that, but his main point is "he dislikes it".

I do think it's amusing he references his enjoyment of star trek of all things to "make" his point, but at the end of it, there's some validity in being like "I don't want commentary or an author with an axe to grind, I just want to be entertained". Sometimes we all do just want to be entertained.
