I've known quite a few black-white couples, although most tend to be black man, white woman. (I've just met my first black woman-white man couple.) Is that typical, do you think, or just a coincidence?
FWIW my husband is Puerto Rican and our two kids look nothing like one another. I've experienced some racism after changing my last name to his, which is ironic. He was born and grew up in the U.S. and I was born in another country, but no one knew? cared? until I changed my name to a Hispanic one. (My naiden name was def. foreign too but not Hispanic.). And now all of the sudden, I've noticed subtle racism. It's quite weird.
Example: Once I was in a crowded doctor's office with DD. I was the only white-looking individual. The doctor came out and read off my name from the chart. I go up to him and he barks at me to sit down and wait my turn. I tell him he just called me and he said "I called XYZ, not you." in a snarky voice.
: I tell him that IS me and he then looked quite apologetic... People definitely have odd expectations on race.
