I can't bypass this comment and give up an opportunity to deconstruct this Patriarchal statement because it's so inaccurate, for one.
A child is not "another man's seed". In case you didn't know, a woman's egg is part of making a child. In fact, the entire process of fertilization, implantation and birth is largely matriarchal. For one, the tail of a sperm falls off to join an egg, which is larger than the head of the sperm. The egg contains the majority of life sustaining material to support the growth of the zygote. The Zygote then implants in the woman, who grows and births the child in her own body.
So what makes a child a man's child as well? I asked this question to the
@Burmese Rice Farmer guy awhile back and he wouldn't answer.
An itty bitty sperm is not enough to call yourself a "dad" or a "father". That is called a "sperm donor".
In fact, I don't believe any of the blood of the father will even transmit to the child unless he has sex with the mother and gives her semen during her pregnancy. If you look at children born to single mothers where the dad was not part of the pregnant mother's life after fertilization, the child nearly always looks just like the mother. Her DNA takes over.
In order to be a "dad" or "father", you have to be part of the pregnancy, part of the birth, part of raising the child, part of the child's memories, part of the child's daily life.
A fatherless child born to a single mother who then has a man come into their life afterward can certainly be spiritually adopted by that man, as if it's his own child. I would say the same is true of the female gender as well. While no one can ever replace a "birth mother", a woman can spiritually adopt an abandoned child to be her mother. It's called LOVE. Love makes a family, not blood.
