Pansexual and gender fluid being acceptable doesnt mean we all become those things. That's not really how sexual attraction works.
Im talking in general here now and not for 7. I'm all for her character being gay or bi or just raffisexual.
I understand how sexual attraction works, thank you. Although we know (even know) that sexuality is a spectrum and is based not only on biology, but environment, situation, and cultural constructions. What I am saying that it is likely that in Star Trek's [fictional] timeline, constructions surrounding sexuality have likely changed. Humans are seen (well off screen lol) engaging in sexual relationships with beings that likely have vastly different sexual organs than our own. So it's very likely that definitions like straight/gay/bi/pan etc., wouldn't exist at least not in a manner we'd understand today. It's more likely people are attracted to other people regardless of what genitals they have going on. Of course that's not saying men & women don't still predominately have relations to propagate the species (though who knows what medical options would be available for people in the 24th century to have children), but Star Trek is a show being written in the present in a very heteronormative culture.
I do enjoy the pearl clutching by a lot of straight male Trek fans who freak at the very suggestion that their favourite characters are anything but straight as an arrow.
