Culture Keeping

I just finished reading a book (I reviewed here) about the phenomenon of "culture keeping". For the purposes of this book, "culture keeping" is the act of a white mother in the home trying to maintain the birth culture of her internationally adopted child. The author's research compared Chinese and Russian adoptive homes. Reading this presented several interesting facts, and subsequent questions:

Facts (from sociological survey):

1) The darker-skinned the person, the more "culture" (in quotes because it is a social idea about culture and not really culture itself) society believes them to have. White people have the least "culture" and it is not so important for them to embrace whatever their ethnicity is. Whites can be ethnic on certain holidays, like St. Patrick's Day or Christmas, but are supposed to be just American the rest of the year.

2) The children adopted from China were easily spotted as adopted in public, and were much more encouraged to embrace their birth culture. The children from Russia could often pass for biological in public, and far less mothers encouraged them to learn/practice being Russian.

3) Conversely, more Russian children's parents kept their Russian given names, or named them other Russian names to honor their heritage. Most Chinese adoptees were given new, American names so that they wouldn't "stand out".

4) Adoptive mothers tend to seek out new immigrants from their child's birth country to assist them in learning traditional culture for their adopted child, instead of from 3rd or 4th generation Chinese or Russian Americans who have assimilated into American culture.

5) African American mothers in the U.S. (parenting their own biological children) have strategies used when raising a minority child in a majority community which would be very beneficial to cross-racial/cultural adoptive families. However, this is not in any adoption literature.

6) White mothers don't know anything (usually) about their child's birth culture, yet are forced to suddenly become experts, giving presentations at school, and teaching their child what it is to be Chinese or Russian. They aren't Chinese or Russian and have no innate knowledge to pass on.

7) The "adoption industry" takes advantage of the monetary resources of the white, middle class adoptive family (who obviously was loaded enough to adopt), and encourages families to include ethnic/cultural traditions in their families for their own financial gain.

Questions:

1) Should we be "culture keeping"? Are we doing it because it's the best for our child? The best for us? What society tells us to do?

2) Are our adopted kids (my family for example) Indian Americans? Is our whole family German-Scandinavian-Indian American even though the individuals in the family would never describe themselves as that?

3) Do we truly see our dark-skinned children as needing an element of "culture" in their lives more than our light-skinned children?

Any thoughts?
