Which might lead you to wonder if any of the complainers actually watched any Star Wars anything (much less any of the novels).
--Politics: baked right into the very core of Star Wars. Hello, a republic grown complacent and clogged with bureaucracy and clinging to tradition is upended by a genocidal authoritarian dictatorship, giving rise to a resistance movement... yeah. Politics, man.
--Strong women: Look, Leia was pretty badass even back in the first movie. She only got tougher as things went along. And now, of course, Carrie Fisher has become more powerful than you could imagine. So, yeah. Not a shock if more tough women are showing up.
--POC: A weakness of the Star Wars movies in the beginning, and a shame Lando Calrissian was the only significant nod to the existence of people other than Caucasians in the beginning -- a lack made even more obvious by the huge diversity of aliens running around. Frankly, it's good to see more human diversity in more recent movies.
--LGBTQ: Basically, see above (though the aliens observation, already a minor side-point of my perception, grows strained here as I'm not sure I remember a lot of alien sexuality showing up either). Cheers to more human diversity. We've got lots of it on only one planet, and how many planets are humans on in the Star Wars universe? Yeah.
Look, provincial and insular people can yearn for provinciality and insularism all they want, but rapid and relatively cheap travel plus the instant worldwide multimedia communication environment of the internet will inevitably keep drawing our world together and exposing all of us to each others' diverse everything. Diversity isn't some weird left-wing fetish, it's a FACT OF LIFE.
So, if someone (hello, social injustice warriors) wants to cling to the past: keep clinging, or alternately stop and admit the plain fact that life is change and change will keep happening whether you rage against it or tolerate it or accept it or embrace it. I know of those four options, embracing is by far the most positive and fun.
The "best" angry clingers could accomplish is dragging humanity back into a primitive insular xenophobic barbarity we haven't even managed to fully exit yet. We're a half-birthed civilization. Don't let the technology fool you. The clingers (Klingons? Wrong universe, but still...) say society has gone to far, but it hasn't gone far enough yet. Being born is the hardest part. Well, until death, but that needn't come for humanity for a long time if we get our butts off this one little planet... but that's another rant and one I come back to often.
Anyhow, angry Klingons: let go of your anger. That way leads to the Dark Side and a big smelly pile of Sith (seriously, that name, geez).
