Were you forced into having that child in the first place? We don't need children for farm work anymore (in first world countries).
How does that play into rape? I don't understand.
The victim of a rape had to play child support. So, he was forced into having a child.
In general, some men are forced into having children by women who lie about taking birth control, or even by collecting semen by used condoms.
Of course in those situations I would hope that a jury could pardon the responsibility of alimony if there was rape involved and the child is not wanted.
