Zero obligations to children is not much better than abortion. At least the child lives but has no father ... which is irresponsible in the extreme.
How about adults be responsible for the child they co-create? Nah, that would be too hard.
“How about adults be responsible for the child they co-create?”
Sure, as long as there is equality under the law. Right now, women can choose on a whim to deny responsibility by aborting their child, or giving it up for adoption. Men have no equal choice in the matter, they are automatically put into a kind of indentured servitude if the woman decides to keep the baby.
I would rather everyone got married and stayed married and lived happily ever after, but that is not the world we are living in, and as long as it is not, there should still be some equal protection under the law.
