Hang on a second.
Has LFL actually dismissed or insulted fans like you specifically? Have they actually called fans like you names?
Most of what I've seen has been LFL ignoring fans like you (I'll get to that in a minute) and only choosing to respond to/call out the genuinely toxic fans who express racist, sexist sentiment about the film.
Other fans who like the film may have lumped you and others like you in with that group (and, certainly in your case, I'd say that's deeply unfair and incorrect), but I haven't seen LFL itself actually just say "Anyone who didn't like this movie is a racist/sexist/troll and we don't give a crap what they think."
What I actually see more of is that the toxic fans seek cover in the crowd of otherwise legitimately unhappy fans and try to make this seem as if they're all being treated equally...but they aren't. I think LFL mostly just ignores the fans who simply didn't like the movie (e.g., fans who wanted to see Luke go kick more butt or whatever, or who think Luke's arc wasn't effectively told). But that's really nothing new. I mean, fans complain about movies all the time without getting toxic about it, and most of the time, the movie's creators just...ignore it. There's not much to be said. They're making the movies they want to make. You didn't like it. Ok, that's a shame, but...it's not like they're going to radically change the direction of their filmmaking to suit you. Certainly, they aren't going to tell you that. Mostly they will look at the numbers and figure that if they're still making good money, they don't have anything to really worry about. I mean, I would have thought that, following Star Trek 09 or Star Trek Into Darkness that you'd see some kind of course correction, but....nah. They just did Star Trek Beeyond and it was (at least what I watched of it before I turned it off out of boredom) largely the same as what came before. Granted, I didn't try to engage in a "boycott" or engineer some social media campaign or rant on a 25-part series of youtube videos about it, but I didn't really see much response to fan complaints, other than JJ's "Warp Nacelle Monthly" comment, especially after the films opened.
Being ignored is frustrating, especially when it's about something in entertainment that you love, but...that's pretty much how these things go. Filmmakers aren't going to respond because, short of saying "You're absolutely right, and the next one will be TOTALLY DIFFERENT!" there's nothing they can say that will make fans happy. And that's before you take into account the effect of warring tribes of fans going at it online.
