As I see it, abortion has to do with whether or at what point the rights of the unborn outweigh the rights of the mother.

Once a child reaches the 3rd trimester, it starts to gain "its rights as an individual."

The support and custody of the child are a separate issue and should be dealt with, in my opinion, with a non-biased view of what is in the best interests of the child, without making assumptions based on the sex of the parent.
