How is this even a parallel?

Courtesy of Pandagon comes this article:

A group of men's rights activists will file a lawsuit Thursday aimed at giving men a chance to opt out of financial responsibility for raising a child.

The group argues that women have more options than they do in the event of an unintended pregnancy.

The gist of the argument: If a pregnant woman can choose among abortion, adoption or raising a child, a man involved in an unintended pregnancy should have the choice of declining the financial responsibilities of fatherhood.

First of all, don't even get me started on how absurd the term "men's rights activist" is.

Second of all, don't some men do this already? Does bringing the law into it somehow make it new?
