I consider myself fairly aware. I've lived in minority (black, hispanic, and Korean) communities for many years. My friends and partners are a diverse array of people from different economic and social backgrounds. I'm totally aware that there's a large economic discrepancy in this country, and that discrepancy runs along color lines. Yes, poor white people exist. Wealthy black and hispanic people exist. I'm speaking in generalities. These generalities are why I get frustrated when people preach a "colorblind" approach to social justice.
We can't create the change we're seeking unless we address issues of race and culture along with economic issues. Issues of race and class are bound up. Intersectionality matters. Feminism that doesn't recognize that the way a black woman experiences being a woman is significantly different than a white woman, or that the concerns of a Muslim woman are different than an atheist, will always be ineffective.
But I have to say, this shocked me. I didn't know it is that bad. And it saddens me deeply to see it.
