That really wasn't clear to me from initially reading your post.
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.
There is no jury in family court, and as the article shows, child support wasn't waived. It's always justified by whatever is "in the best interest of the chilllldrrreeeenn"
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.
