I'm half black... Is it wrong that I identify as white?

You're literally half. I don't blame you at all.

Because the black dominated and cancels the white. You will never look white.

You are technically a MULATTO.

White refers to Europeans, Middle Easterners and Hispanics who are direct descendants of Spanish people.

If your skin is white you are white

there's nothing "technically" about it, nothing to "consider", no such thing as race without purpose-breeding

If you identify as white you will lose your black privilege like affirmative action policy.

That's really sad that you'd basically deny one of your parents behind their back as well as their side of your family tree! However, because societies as yet again proven that despite BS black people about being accepted they've turned their backs on us, only this time it would appear to be for good, so I hope you are also happy with your choice too?

That's your choice .. but why ?

Identify how ever you want to identify.  Nobody cares.  Literally nobody.  It's totally up to you.

Because whitey is the devil and blacks are kings.

You can identify as either black, white, mixed, or any of them! Nothings wrong with feeling or identifying as white if you are partially that race. Same goes for feeling or identifying as black
