What about married couples who want to lovingly open their homes and hearts to these children? I have been seriously considering adopting an older child (there is no shortage of people looking to adopt infants). I won't do this until I am married (to a likeminded person), but I don't understand what is selfish or immoral about a couple bringing children into their home who would otherwise languish in foster care.
I've always regarded it as beautiful and special, and I don't really think infertile couples should have a monopoly on loving these children. It certainly doesn't hurt the children, unlike homosexual and to a certain extent, single parent adoptions.
I believe I said in most cases. Of course there should be exceptions. My wife's brother was adopted. My wife's parents had two daughters and wanted a son; however, my mother-in-law had been told that her life and the baby's would be at risk if she became pregnant again. My father-in-law is a physician and he was told of a young unwed mother who was unsure of what to do (she may have been contemplating abortion, but I don't know). My wife's parents paid the young woman's medical bills and adopted her son.
