But the man IS required to support the child the rest of his life at least where I live.
You're not quite understanding my argument, here. Men aren't expected to support the child
anywhere near the same degree as women are. Again, at the
absolute bare minimum a man is expected to financially support the child and mother. That's it. By comparison, at
the absolute bare minimum, the mother is expected to carry that baby - with all accompanying health, personal and financial impacts that entails - and then
continue to raise that child from birth to adulthood, supporting both personally and financially for as long as she lives.
The social expectations are nowhere near comparable. What you're complaining about here is like complaining that fathers are expected to do something that requires not even the slightest fraction of comparable effort of what the mother puts in.
My question is why does the mother get this choice but not the father?
Because the impact on them is greater, obviously. If they choose to carry the baby to term, they are choosing to take on a significant amount more responsibility (as well as a significant amount more stress, both financially and physically) than a father (at least, at the bare minimum) is expected to.
Think of it this way. If a woman has a child and the father chooses not to support it financially, how does society feel towards that father? Like you said, they're often ostracised and called a deadbeat dad. But, for the most part, society just looks down on them a little. What if a mother decides to completely abandon their baby and not support it in any way (say, leaving the father to raise it)? Do you think that society would be
just a little more harsh on that woman than they would that man, despite the fact that they're both doing more or less the same thing?
Being a deadbeat dad is seen as being bad. Being a mother who abandons their baby is seen as being an absolute, irredeemable monster.
They both have a burden to support the child but only the mother has an option to not support the child.
You keep ignoring the DEGREE of support that is expected. You can't equate these things. They're not the same expectations.
They have the same reasons for not wanting to take care of the child.
Irrelevant. The mother makes the decision because the majority of the burden is on them, regardless of the father's role in bringing up the child.
