Being of mixed race, in the current society where victim status is currency, only confers benefits. One of such heritage has the option of passing as white to avoid superficial prejudice, passing as black on job applications and scholarship applications, and blogging about how nobody is capable of understanding the horror she goes through every day (generic feminine pronoun used here for style, because you know she is going to do the same).
The only workable way to defeat racism is to keep breeding till we are all the same color.
