My mom is a Maori who immigrated to American from New Zealand in the 70s. She married my dad, who is as white as white can be, and had my sister and I.
My sister and I are white as hell. Pale skin, blue eyes, anglo features, My sister has thick beautiful dark hair, but mine is thin and bone straight. We've always identified as white, because we look white, and it's a pain in the ass to try and explain what a Maori is (New Zealand indians sounds kind of demeaning, even to me). There are no real benefits to claiming to be biracial when you're white / Polynesian, so why bother? I'm very proud of my mothers side of the family and have done a lot of research into our genealogy. I'm proud to be half Maori, but it isn't one of my defining features when I tell people about me.
I was talking to someone on a forum the other day, and the issue of my heritage came up. I told some interesting things about Maori culture (the facial tattoos, the hakka, hunting moas, the green stone and bone carvings, basic stuff). When he asked how I felt about being biracial I said I didn't really feel like I was. I said I was white, and that I identified myself as an American. This guy lost his shit. He accused me of white washing my heritage, and that I clearly had internalize shame about being "not anglo". I was kind of shocked because the guy had seemed reasonable, up until he started all this Tumblirina double talk about how people like me were causing "real" biracials to be scared to admit to it.
Holy fuck dude.
