I've never heard the dee gender/sexuality stuff before? i love this theory.. where's the discussion at
oh man! sadly i don’t think... anyone has ever really written huge in-depth posts about it? at least not the way there are big posts about trans charlie, nb/genderfluid dennis, etc, because we as a fandom are really Not Good at talking about dee
anyways, that being said, there are a lot of different interpretations of dee’s gender and/or sexuality floating around, even if none of them (as far as i know) have been expanded into huge meta posts yet
she’s not super like? invested in being feminine? like when dee does try to play up her femininity it’s almost always either because the guys are making fun of her, she needs to do it for a scheme, or because she’s otherwise feeling pressured into it. that’s prompted some people to view dee as being agender-- this one is @itsalwaysgay‘s personal favorite theory, so i would go to them if you wanna hear more about that!
trans girl dee is also somewhat popular, due to both the above disdain for femininity and (i would imagine) the comments the guys make about how large and gangly she is.
looking at the sexuality side of things, a LOT of people see dee as being either bi or a lesbian-- which one you personally see her as really seems to be more of a personal taste/interpretation thing.
the canonical evidence for both of these is that dee never seems particularly interested in men? and when she does it’s almost always because they’re hot or wealthy or desperate and not because dee’s like... legitimately attracted to them in any way at all. the symbolism of her fantasy in the gang saves the day is also preeetty strong evidence in my eyes that she has some sort of attraction to women in her subconscious, even if she doesn’t consciously act on it.
the point that it splits is whether or not you personally interpret dee’s relationships with men as being motivated by physical/sexual attraction or by compulsory heterosexuality fucking everything up as it tends to do. if the former, you’re team bi dee-- if the latter, team lesbian dee.
i do have trans dee and lesbian dee tags, if you’d care to look at those! sadly though the trans tag is currently just one playlist and nothing else
if anyone has things to add, or links to actual Big Posts about any of these headcanons, i’d love to see them! it’s possible that they do exist and i’ve just missed seeing them
