Biracial Identity: How will people know who they belong to?

With the election of Barack Obama back in 2008, I heard many white people get upset and proclaim that "Well he's really biracial, not black." anytime it was mentioned he was the first black President of the United States.   They held on to that "his mother's white!!" ideal for a really long time.    If you don't know, the President identifies as black.

I totally understand now.  Many white and biracial people like to say that black people hold on near and dear to the one drop rule, the rule in which if you have one black biological relative, that essentially makes you black; however with two biracial children myself, I can guarantee you, white people hold steadfast to this rule as well.

I'm going to be perfectly blunt, skin color wise, my children are lighter than me, pretty significantly lighter than me, but they are also significantly darker than their father.    It's crazy, but they are a color that is a mix of his whiteness and my blackness.  Let all that seep deep into your minds.

My daughter and son both have my brown eyes, and not their father's green eyes, both of them have hair lighter than mine.   However, no one ever questions if they are mine.  No one has ever asked me how do people react when they see me out in public with my children, no one has ever assumed that people will assume that people will mistake them as someone else's children when they are with me.  However, people CONSTANTLY ask if their father has experienced this. If you look at my daughter and my son, they do kind of look like him.......probably because HE'S THEIR FATHER.  However, because he's white, and they look less than white, he must run around getting strange looks and people proclaiming they aren't his children. This has never happened, but white people always assume that it does.  I've never had a black person say this to me.  Ever.  I've been asked by black people if they are "mixed", but otherwise it's been crickets in regards to them assuming that either me or their father have a hard time with people identifying them as our children.  

Shout out to all the nice white people who don't think my white husband kidnapped his own children; or should I say shame on you mean white people for turning the other cheek at a white man stealing brown children because in your mind brown children don't matter.

I now understand why biracial people tend to identify as black, just not due to societal prejudices (we all know they can't do the same things as white kids and get the same treatment), but because mainstream society sees them as black no matter what.
