When you watched a woman carry a baby for 9 months, deliver, breastfeed and care for the child 24 hours a day for years, teach a child to be kind, make sure the child is well rounded, give all she has to make sure her child feels loved, there’s no mistaking their unique value in the lives of their children. I’m a very involved father and love my kids, but as a biological man, I don’t hold a candle to what my wife (a biological woman) can offer my children. Biology is unbeatable. Science.
