I’ll chip in my own experience as well. It’s not direct experience, but I was an interested bystander if you will.
Both of my mother’s sisters adopted children. Both adopted all of her children. In one case four children, in the other five children. None of those children were white (as my aunts are). In ethnic breakdown they are: three black daughters (they all prefer “black” to “African-American”), three Hispanic sons, one Hispanic daughter and two daughters of mixed ethnicity (one black-Korean and one black-white).
My mother and her sisters are all quite close, so my lily-white brother and I grew up with our technicolor cousins. We were aware that they all had periodic brushes with racism and bigotry (I mind one moment when a lady in a mall when I was about five attempted to take me away from my older cousin who was watching me as she thought my black cousin was “stealing” me, as red-headed baby girls shouldn’t be in the charge of black teenagers. I’ve always wondered for what purpose she thought my cousin was stealing me as my cousin was about 14 at the time :dubious: ). Both of my aunts conciously decided to introduce their children as much as possible to their biological heritage. This was child’s play for one aunt (who lived in Harlem in NYC) and slightly more difficult for another (who lived in a predominantly white suburb of Providence, RI). They all made a point of making sure their children knew of historical figures of importance of their ethnic extraction, and had interactions with people of many different cultures.
We’re all adults now (my oldest adopted cousins are in their early 40’s). I’ve spoken with all my cousins about the issue (it comes up from time to time and I’m a curious sort) and with two exceptions, they are all deeply, truly grateful that they were given loving homes. They consider my aunts (and their spouses) their parents and the rest of us lily-white folks their family. The two exceptions: one of my cousins is schizophrenic. One doesn’t discuss matters of this nature with her - it’s futile and pointless and cruel (as it’s likely she inherited her disease from one of her unknown parents). The other one would bitch if she were hung with a new rope.
Whether or not my adopted cousins have sought out their birth parents or remain connected with the culture associated with their ethnic extraction depends on the cousin. Some have and some have not - all were provided with as much information as my aunts were in possession of and allowed to make that call for themselves. (Keep in mind that the adoptions took place quite some time ago, and information was seriously lacking. In the case of two of my cousins, they were merely left on the doorstop of a monastery in Brazil as infants. No note, no names, no identifying information at all. Physically, they appear to be South American native in extraction, but they check off “Hispanic” on census forms.)
Discounting my schizophrenic cousin, all are happy, well-adjusted people going on about their lives, content in their upbringing and background. (Okay - generally happy people - ain’t nobody happy all the time.)
Just for fun, I’ll pass on the adoption anecdote o’ the year with my family.
Last summer, the children of two of my adopted cousins were playing outside one of my aunt’s houses. One of them (of black and Hispanic extraction) turned to the other (of black and Korean extraction) and asked “Miles, are you black?” Miles looked very thoughtful and then shook his head and said “No, Alex, I’m green” and went back to his ball. When asked later about his response, he informed us that as he wants to grow up to be Kermit the Frog, he must be green.
We almost died laughing.
