I've been thinking about this all day, and I've decided to go ahead and share this. I hope that's alright with everyone here.
When White America uses Asians as tools against Black Americans, it's a lot more personal issue to me than most Asian Americans I think. I grew up in a very white part of the country, as the only Chinese-American kid in my town. It's really confusing growing up in a place where what you look like, what your home life is like, what you've been taught about your heritage is completely alien to everything else around you. Thinking back on it I had a lot of identity issues as a kid, hell I thought I was white until like second grade.
As I grew older I started noticing things white people started saying to me like "you're not really Chinese, you're basically a white guy" and "Are you going back to China when you grow up to find a wife?". It made any shame that I had for my race worse, and pretty soon as a young teenager I was playing the part of an Asian jester. In the AAPI community it's not an uncommon phenomenon to know an Asian that really plays up stereotypes and makes fun of themselves so they can try to score brownie points with white people. I was that guy. One of the things that finally saved me was my friend, who happened to be black.
In middle school I met a guy "R" who was the only other non-white person in my honors classes. You know, instantly there's like some common ground right there, so we became friends, and later on best friends (to the point where I was the best man at his wedding much later on). Along the way I went to church with him occasionally, I ate with his family, and went to barbecues with his friends. Though the black community where we were wasn't huge, it was sizeable. He was...really different than me lol. R's parents marched during the 60's, and he was always proud of who he was and where he came from, and in his community I finally felt what it was like to be OK with being different.
One day at lunch after I did something particularly embarrassing I remember R pulling me aside afterwards, and asking me if I realized that to our white friends "I wasn't telling jokes, I was the joke". It's one of the things that started my journey to accepting who I was. To this day I envy R for the support that he found in his community. The...feeling of family that I got from R's community doesn't have a 1:1 analog with AAPIs that I've found, which still saddens me greatly.
So when I read some mouth breather on Reddit or whatever spouting off about how black people only get in to whatever program because of affirmative action, it seriously pisses me off. R and I worked our asses off to get where we are today; to not only try and cheapen his hard work because of jealousy and prejudice but to use my demographic to do it... it makes me see red.
Anyways sorry for the wall of text.
TLDR; I'm Chinese, my brother from another mother is black.
