This is where subconscious racism rears its ugly head with me.
I was raised in a lily-white town (as in, we had one black-white mixed-race family and a few Chinese folks who mainly ran restaurants. According to the Census Bureau via Wikipedia:
"96.94% White, 0.45% Black or African American, 0.08% Native American, 1.43% Asian, 0.01% Pacific Islander, 0.20% from other races, and 0.90% from two or more races." (2000 census)
And my high school was a hotbed of racism thanks to forced busing (or "school integration", if you prefer.) I was a member of a hate group myself (I got better.)
When you've got that drilled into your head from childhood that interracial relationships are wrong or unnatural or a good excuse to vent some teenage-boy frustration and beat the shit out of a black kid without the principal giving two shits (and I'm from the Northeast!)...
Well, it's gonna lead to certain visceral reactions as an adult. And I just can't get past that drilled-in-childhood revulsion at the sight of an interracial couple (and indeed, it's black guy-white girl that triggers that response in me---if I see a black guy with an Asian or an Asian with a white or any other combination, it doesn't register as unusual with me.)
I'm sorry, I really am. I try very hard to move past that. But if any black people (I won't say "African-Americans" because I'm sure an African in the UK or a Jamaican or...you get the idea...reading this would take offense) want to hate me for that, I honestly don't blame you. And if you've any advice for becoming more accepting, I'm open to it.
