I don't know what to make of your comment. The kid's 18. He had no choice in any of this. His mother made a foolish and selfish decision. He got screwed on this thing. I have seen the rootlessness and rudderlessness of people without Dads.
Not all children born to using sperm donors are without fathers. Most are born to households with a mother and father. I'd say it takes a big man to go this route.
What child has a "choice" ab out being born?
