No, she wouldn't be. She's the Mother of Dragons, because she's Targaryen/Valyrian. The Targaryens are white; GRRM's made that explicitly clear. Not just white, extremely pale white (as lofty, ancient, magical races so often are in fantasy, because they're a product of a culture that valorizes those traits). It's possible that GRRM could have made the his ancient, magical race of dragon riders black, yellow, or red - but he didn't. And he's part of a culture that overwhelmingly tends not to.

Er, yes. Overthrowing their culture because she views it as wrong. "But the practice is evil/harmful/wrong!" has been the rallying cry of many European colonizers for centuries. It's still used today to justify things like banning the hijab - obviously, those women are being oppressed and we have to save them!, etc.
