I think I realized I was mixed pretty early on. Though, my skin is dark and I probably look more 'black' than anything else, I was born in Honolulu, Hawaii, amongst my, mostly, Filipino side of our family. My mom is half Filipina and half Black, while my dad is 100% Black. I can remember in my teenage years when I was in an interracial relationship with a caucasian girl. One of my female, African American classmates asked me why I did't want to date someone that looked like my mom--as if my mom would be offended by me bringing home someone that wasn't black. My classmate, obviously, didn't realize I was part black and part Filipino, nor had she ever seen my black and Filipina mother before. Basically, any relationship I could find myself in would be interracial--which is fine by me.
I feel that I identify with being both black and Filipino. My outward appearance, unlike some of my siblings, leans toward African American rather than Asian, so I suppose that internal identification could be ever so slightly stronger. As I think about it, I may even over compensate for that by making sure that I am fitting at least some of the traditional Asian American stereotypes (fluent with a pair of chopstick).
Now that I am father to two mixed race kids and husband to a caucasian woman--all of whom I love dearly--I feel that there is some onus on me to make sure everyone in the house knows that there could be some biases and stereotypes to come. I have found myself educating my wife on some things that I assumed she knew and vice versa. Two years into our marriage and parenthood, it has been a learning experience already and I'm sure there will be more and more experience to move the learning curve in our favor as time goes on.
