Your post is incoherent.  You write:  "I don't know that you can afford to see the similarities."  Between what and what?

Oh.  The similarity between: a) a statute that punishes a man for having orgasmic sex with a woman when he doesn't want a child and b) a statute that punishes a man for abandoning a child he's fathered?  Much as we both abhor fornication --- actually, I doubt that you do --- what meaningful similarity is there between the two statutes?  Suppose the man who doesn't want the child at the time he has sex later realizes that since he fathered the child, now he must support it. You would send him to jail --- even if he supports the child --- simply because he didn't want the child at the time of the sex act?  But you wouldn't punish a woman who not only didn't want a child when she had sex, but later aborted?  Nuts.

You also say:  "Women who have sex can get pregnant and not even remotely get a biological bang out of it."  You have a low opinion of womanhood.
