Joesph….
She considers herself White/Jewish American because she was raised in that type of family since before she could talk or walk.
There were many American Jews adopting baby girls in China when we did. The China 1 child policy led to many women giving up female babies for adoption hoping to have a male they’d keep.
Daughter had rejected Chinese language lessons as a child (commonly taken by adoptees in America), and until last year never expressed interest in a visit to the land of her birth. I’ve been to China about 20 times on business in the past 35 years.
She did not befriend other Jewish Chinese here in school or summer camp and just considered herself one of the family.
We always joked that when we went to fancy Kosher Chinese restaurants that had Chinese waitstaff that daughter was the one who needed a fork, while parents used chop sticks and mother could order in Chinese.
It’s all about Nature vs. Nuture.
BTW>>>we also have a domestic white adopted daughter who did seek out her birth parents at age 19 and was rejected by them. The Chinese born daughter will never have the opportunity as there were no records kept of these births. They usually took place at home and the babies were left on the step of the orphanage during the night sop the birth mother could not be arrested for violating the one child birth laws.
Our Rav suggested that we never consider a Jewish baby when adopting so the child need not worry about Mamzerus when shidduch time came. Having a child of another race lessens the problem further.
