waaahhh it's all wonderful and I'm so happy it's a part of... well, ok I've always assumed queerness was part of the universe, but it's part of what they're actually showing us through the screen, and that's delightful.
Star Trek has always been important to me. I'm autistic, and the token autistic-coded-but-not-explicitly characters on each show (Spock, Data, Seven, etc) have always made me feel seen — and though Tilly is also not explicitly autistic, Mary Wiseman has shown delight in folks reading that from the character.
I'm trans, and the various bits of trans representation in previous shows (TNG: Outcast, ENT: Cogenitor) have been... uh, rough. Adira and Gray not only being trans in-canon, but played by trans actors is... it's huge. it shouldn't be, but it is.
and speaking of the Tal symbiont, I'm part of a plural system. the Dax symbiont touched a little bit on this, sure — but oof, DSC: Forget Me Not? we sobbed through half of it. just terrifically gorgeous and accurate and something we'd never seen on tv before. systems get... a pretty bad rap in media, with things like Psycho, Legion, Split, etc... and this tremendously positive depiction is a gift. (waiting to see how Rios in PIC shapes up — easy to read that holographic crew as the manifestation of a system)
