I've seen tons of threads asking whether it's ok to date/marry someone of a different race.
But I don't ever think I've seen a thread about whether or not it's ok to adopt children from another race... (I know that question is clearly answered in the posts here as well, but still... I see it as an interesting twist.)
My parents have a few kids who are not the same race as they are. I happen to be one of them. And neither myself nor my siblings married anyone who was the same race as themselves. Although I am no longer married, I have never dated anyone who is of the same race as I am.
This wasn't because of any special preference, but more about proximity. The only guys (maybe 4, at most?) I've met who were the same race (and there were very few of them) were taken, just a good friend, or rejected me because I'm not a "pure" Asian (because I'm adopted, have a bloodline that's "tainted", and do not come from a traditional Asian family.) I could not marry into a family who did not accept me for who I am and wanted me to be something I'm not (a "real" Asian), but that's just my personal opinion.
I do understand what you're saying, Elijah, because although my family adopted me, certain older members of my family have the same feelings as what you described in your original post. Some races are "ok" and some are "forbidden", which grieves my heart terribly. But my parents are accepting of anyone, and to me, that's what would count the most.
I once dated someone who was on my older family's "unapproved" list of races, and I brought him to Christmas dinner. I told my family in advance that if anyone there so much as looked at him funny, we would be gone in the blink of an eye, because I wasn't subjecting him to that nonsense. But my thinking at the time was, My sibling's dates are being accepted (they were on the "approved race" list)--therefore, I'm going to try my best for equal treatment. Our relationship didn't work out, but my parents treated him as part of the family while we were together.
It is what it is. God's taught me to be me--and I'm happiest around other people who feel the same way about themselves as well.
