Any racial definition can become complicated or muddy, Who is Black certainly has (as evidenced by this thread). I just meant to point out that Who is Black? is complicated, so Who is Multiracial? being complicated shouldn't be a reason why people should only call themselves Black.
And I suppose your view of the websites I posted being fantasy is a common thing we can't agree on. Again and again it's become evident the main argument is what you see as fantasy is mine (and others) reality. And I am sorry that any of the websites I posted offended you, all of them are only websites/forums/organizations that support a racially mixed identity and fight for the protection of rights of racially Mixed people.
I don't think MLK and Malcolm had to "center" their message around being mixed. That is something we have to disagree on.
Just like we will have to disagree that when people embrace a mixed identity they are moving further from being Black and can't also fight for Black rights and be just as effective. I see them saying they are not just Black as just reality, people knew Malcolm X was not full Black by uh..looking at him. I don't think if he had accepted that openly it would have been an affirmation that something is wrong with being Black. It was just who he was, and our racial backgrounds should not have assumptions attached. "If you specify or even acknowledge you are not unmixed Black, if you aren't, you are saying there is something wrong with being Black." I don't think it helped the Black cuase denying that Whiteness by only calling himself Black. I'm sure there are plenty of Multiracial activists today who also fight for Black rights and are effective.
And I do thank them, I just don't think having to stay in the mindsets of racism that they themselves fought against is the best way to honor them.
