I think it's just a bit too early to have homosexual relationships in such mainstream films like Star Wars without rising suspicion of it being just a hip move or excessive political correctness or a jab at conservatives. These things take time, in 2 or 300 years we won't have these discussions anymore.
The day we stop praising or condemning these kind of things in movies as "progessive" is the day we realize they're just supposed to be normal. You know the war is won when we don't notice this stuff anymore; that doesn't mean lowering our guard or halting the discussion, but making the level of inclusiveness of a movie or product a big talking point every single time is a way to make something that's supposed to be the norm controversial.
It's been 41 years. It's not "too early"
I don't give a shit about the feelings of bigots.
