The fuqqer isn't a father, he's what is referred to as a sperm donor.
My wife and I met when my (now adopted) son was 1.5 years old, when I adopted him 3 years ago, we never heard from the sperm donor (I think his trailer-dwelling-legal-advisor/Mom was going to advise him not to sign papers).
Anybody who turns their back on their child should be castrated, they prove it once that they can't handle having children, so they shouldn't be allowed to procreate.
