I believe she is Arab. Arabs are Semitic, which is indeed one of the three main Caucasian sub-groups. They are happy to self-identify as "non-white" and "non-European" though. She has made these claims about herself, and who am I to argue with her?
She should be rounded up with the rest of her tribe and repatriated back to Arabia.
Maybe brats like her identify as non-white. I’ve got friends and relatives of Arab ancestry. They definitely identify as white.
