^^ It all comes down to the idea that rationalizing the inconsistencies in Star Trek used to be fun -- it's what we fans did in the 1970s thru 1990s. It was fun; it was a game...
...e.g., "How can Khan know Chekov?" -- Answer: "Chekov was on the Enterprise during Space Seed, but below decks."
Today the opposite is true -- people try to make a game out of nailing those inconsistencies to the wall and framing them for all to see, and screaming "Aha! This proves Abrams/Orci/Kurtzman don't care"
. Some fans today are taking the fun out of trying to rationalize the inevitable inconsistencies.
