I didn't read all of the original post because it was quite long, but I'll say this:
My ex girlfriend is Chinese. I am a mixture of Native American, Spanish, and a whole lot of white-European. At first, she was weary of dating me because she had only dated asian guys in the past, and her parents always told her to marry a "nice, wealthy Chinese man." Well, after a long time of just being fuck buddies, we became quite attached to each other, so she decided to introduce me to her parents. Her parents LOVED me, so finally she decided that it was cool for us to be "official."
About a year later, after we broke up, she went on this fuck-every-guy-she-sees spree, and they all happened to be white males. Her current boyfriend is a white, jewish blonde. One day I asked her why she was no longer attracted to asian guys, and she said, "Well, you introduced me to big dicks. Besides, I despise being asian, and dating another asian is just...ew!"
Despite the twisted compliment she threw in there, I was quite sickened by what she had to say. Here she was, the same girl who used to bring me asian porridge for breakfast before school; the same girl who I used to eat Spam and rice with; the same girl who would translate for me whenever we would go eat Dim-Sum, saying, "I despise being Chinese." Now she's COMPLETELY white-washed, even going so far as trying to adopt a British accent!
But once in awhile when I hang out with her, I STILL catch her switching her L's with R's, and it just let's me know that her own heritage will never completely escape her.
