she shares a lot of the best traits of the other mane 6>hard worker like Applejack, runs a successful business on her own which has got her all the way to Canterlot>unicorn master race, can use magic, albeit not at Twilight's levels>able to make decisions and take the lead, she is a bit of a planner and organizer >she can be as kind as Fluttershy without being a pushover>she is willing to fight, even physically, for what she cares about
She is the most mature out of the m6, yet people always say that she's a cunt.
Yes, sometimes she gets too much focused on her work, but so do AJ and Twilight, yet all they need to do is bucking apples and reading, while Rarity has to stay afloat (in fact, rising above the others competitors) in the harsh world of fashion.
She takes care of herself and sometimes acts selfish, but she's not nearly as egotistical as Rainbow Dash.
She is a bit of a drama queen and someone could say she acts "girly", but for example complaining about getting dirty isn't really that annoying and mostly she acts lady-like, a thing which I appreciate a lot.
Also those accusations of being manipulative are stupid, every woman is like that or even worse.
What else? She is a good sister, as we've seen in a few episodes now. She is quite an easygoing pony, she leads a music group, she cares about Ponyville and contributes to the city's life. She loves her friends, otherwise she probably would leave Ponyville and go to Canterlot or Manehattan, where her work is more appreciated.
I'm not saying she's completely flawless, but that's why she's even more interesting as a character.
As an Anon once said:>She may seem like a cunt, but she's a warm, squishy, comfortable cunt. The kind of cunt you wouldn't mind sticking your dick in then leaving there and holding in your arms as you drift off to sleep in each other's embrace.
