The parents gave up their children anonymously for some reason. They should be afforded the right to privacy (a right so exhalted by the abortion loving left) from having their personal information revealed after having been assured it would remain private. That being said, it would be beneficial for adoptive children to receive medical information if that could be done anonymously.
The birth parents have the option of asking to remain totally anonymous. They are being asked for medical information.
I know a adoptee who was told that her birth mother left a letter for her. The state has refused to hand it over because she can not produce her original birth certificate with the birth mother's name on it.
Now she can get her letter.
There is right to privacy. And then there are very stupid regulations that keep people who would like to be reunited apart.
