I'm guessing average HNer's see "girl", and think to themselves "must stamp out any sexism by upvoting anything remotely related to females". Reverse sexism at it's misguided best...
Sexism, like evolution, has no reverse.
I'm usually the first person to denounce reverse sexism, but I loved this article. It has nothing to do with this young person's gender and everything to do with her attitude.
There is a solution to this: you can flag the article if you feel something is fishy. Gumming up the works with a pointless question doesn't help anything. I'd encourage you to continue to contribute rather than being that which we want to discourage.
