For all we know there may be more gay people in Star Wars than straight. It’s just the straight characters talk on screen about it.

This is true, really the only sexual relationships we ever see in the films are Han and Leia, Anakin and Padmé, and Owen and Beru. Other than that, Luke and Lando both display interest in Leia, and I guess Jabba and Sebulba have weird interspecies shit going on (attraction to female twi’leks seems to be almost universal). So we’ve got six characters involved in heterosexual relationships, and another two who are shown to be attracted to the opposite sex. Literally everyone else could be gay for all the information we’re given (and any number of those eight could just as easily be bisexual as straight).

EDIT: Before this gets misinterpreted, I want to clarify that my point isn’t that Star Wars doesn’t need to add explicitly LGBTQ characters because if you want that you can just decide in your head that General Madine or Lobot or whoever else is gay. What I mean is that depicting a homosexual relationship isn’t going to have a disruptive effect on the story because romantic relationships are of secondary importance to the narrative (well, except for Anakin and Padmé, and we all remember how that went over). Beyond the fact that a Skywalker is probably going to have to reproduce at some point if the numbered episodes are going to continue beyond the ST, nothing hinges on a character’s orientation anyway, and so I see no reason not to be inclusive.
