She can choose whatever ethnic background she wants to. But, is it really necessary for her to describe her physical appearance- what she looks like and what she doesn't look like? What race of people she hangs out with? Is that necessary?
No its not necessary but why make such a fuss about it? You can tell from her post she's young and naive and her post is quite tame compared to some of the others we see on here. You're gonna burn yourself out fast.
