Well as prospective adoptive father... In some ways... Yes. That was part of our adoption training. To learn that many adoptees want to know their biological mom and dad and suffer greatly if they're not able. An adoptive father can provide all the emotional support in the world and the day to day fathering, but he can't provide the biology, whereas a biological one can provide both the day to day fathering and the bio connection.
It's not a popular sentiment... But it was required as part of our certification in california. When separated from mom and dad, they call it the primal wound, but our society accepts separating children from one parent without any of the guilting they require adoptive parents to go through.
From a purely empirical standpoint, in aggregate, biological father's are the least likely to hurt or kill their children. Both adoptive father's and step father's are more likely to. Says nothing about individuals, but as a society it would behoove the powers that be to ensure most kids are raised by bio parents. And by far most states adopt this approach, even to the point of absurdity.
