Jo March isn't a tomboy, she's Transsexual
Amy: "Don't Jo. It's so boyish!"
Jo: "That's why I do it."
Jo: "It's bad enough to be a girl, anyway, when I like boy's games and work and manners! I can't get over my disappointment in not being a boy."
Beth: "Poor Jo! It's too bad, but it can't be helped. So you must try to be contented with making your name boyish, and playing brother to us girls."
[Jo had] the uncomfortable appearance of a girl who was rapidly shooting up into a woman and didn't like it.
Jo: "I'm the man of the family now Papa is away."
Jo: "I'll try and be what he loves to call me, 'a little woman' and not be rough and wild, but do my duty here instead of wanting to be somewhere else."
No gentlemen were admitted, so Jo played male parts to her heart's content.
...Jo, who didn't care much for girls or girlish gossip, stood about, with her back carefully against the wall, and felt as much out of place as a colt in a flower garden. Half a dozen jovial lads were talking about skates in another part of the room, and she longed to go and join them...
Laurie: "There isn't anyone I'd like to see. Boys make such a row, and my head is weak."
Jo: "Isn't there some nice girl who'd read and amuse you? Girls are quiet and like to play nurse." (note how she almost seems to be responding to him as a boy, and talking about girls as "other")
Jo: "I'm a businessman - girl, I mean."
[Jo] seemed to understand the boy almost as well as if she had been one herself.
Laurie: John is going home with you, as I can't.
Jo: No need of that. I am not a young lady, and it's only a step.
Jo felt as if during that fortnight her sister had grown up amazingly, and was drifting away from her into a world where she could not follow. (world of womanhood)
- Uhhhh, no. Since that sort of defeats the entire point of her character, which is that you can be spirited and tomboyish and that does not make you any less of a woman. She's a nontraditional girl rebelling against the strictures of what is expected of women of her time, which is why she wishes she were a boy — she'd have more freedom that way. Her whole arc is about finding her own freedom (see: her career as a writer and resulting financial independence) as a woman in a Victorian society. You aren't less of a woman if you're a tomboy or don't otherwise conform to "ideal femininity", which is the entire point of Jo's existence as a character.
In the musical version, Jo March is the Slayer.
- She cuts down a Christmas tree and drags it across the street in about four minutes
- Clarissa - tell me this doesn't sound like something a slayer would write. "There's no escape. She's but a child! And yet she turns to fight with eyes ablaze! This noble girl meets his gaze unafraid! She will not be defiled." Not to mention that Professor Bhaer, who's been calmly sitting and listening up until this point, doesn't object to her story until the male hero comes in to rescue Clarissa. When Jo rewrites it with a female Roderigo saving the day, Bhaer has no objections to the story, despite it still being a sensational story.
- This exchange with Aunt March:
Aunt March: You spend all your time writing senseless stories, constantly trying to save the world, when you can't even save yourself!
Jo: I don't need saving.
Aunt March: You'll marry! All girls marry.
Jo: I'm not all girls.
- The reason she's so reluctant to accept Laurie's friendship at first, despite taking to him immediately, is because she thinks he might be a vampire - when Mr. Laurence came by the house, Laurie just kind of hovered in the doorway, and he basically never leaves his house.
- Come to think of it, did the Marches ever specifically ask Laurie into their house? For a vampire can't enter into anyone's home without being invited. No exceptions. Ever.
- Another story she writes: "Carlotta, the madwoman in the attic, a creature of gall, hungry for blood, rose from the darkness. Her skin a ghastly white, her eyes a beady red, her fingers clutched with rage as she went out into the wretched night..."
Beth is somewhere on the autism scale.
- She is afraid of talking to strangers, clearly struggles in company and was unable to cope with school to the point her mother decided to educate her at home after seeing the meltdown just one day caused - social anxiety. She has set routines, particular activities she loves (her piano playing and the dolls she takes care of), and generally seems slower to mature than her sisters.
