That is a very silly thing to say. My wife, who was adopted, and who later gave up a baby for adoption, would tell you that in much stronger terms.
I was raised by a single parent and grandparents. I raised my daughter as a single parent after my wife died. At no point in either of our lives do either of us regret that.
Now should my mother have given me up because Dad went banging half the WAC corps or should I have turned my daughter over to strangers?
Because I would really like to know.
