How can you get out of a cult and use loaded language like sjw?
That aside, and the fact you’re frightened by diversity (hell, women will want to have responsibilities in the Congregation next!)...
Rey is not a Mary Sue. Compared to Anakin, her abilities are far more logical. But apparently testes allow a nine year old to fly podracers at 1,000km/h and fly a spacefighter, as well as being an ace mechanic. I mean, an attractive 20ish women by herself on a frontier planet would never have learnt how to defend herself, nor have depended upon her technical skills to eat, and the fact she even says she’s flown spacecraft sub-orbitally probably got missed with her boobs getting in the way of some men listening.
