Still weird ideology.....
I agree. And I think I can pinpoint exactly why it seems weird. It treats the woman as a possession, as property. Her own desires are irrelevant here. The man, the rapist, is guilty: he has made use of property that doesn't belong to him. He must pay a fine, but not to his actual victim (as we would see things); rather, to the victims owner -- her father. That's because, from that point of view, it's the father who is the principle victim, not the woman. He had a right to sell her on the marriage market as a virgin, and the rapist has deprived him of that right. And the rapist is also required to marry her, because, being reduced in value on the marriage market by loss of her virginity (for which he is responsible), it's not that likely anyone else will. And he's not allowed to divorce her, either. (Of course, she wouldn't be allowed to divorce her husband under any conditions -- women were property. Property doesn't cast off its owner.)
While it was rare, I think, for an agrarian-age culture to actually require rapists to marry their victims as a matter of consistent law, similar attitudes prevailed throughout the world. They are embodied in all of the so-called "great" religions, all of which emerged during the agrarian age of civilization.
The only real good any of this served was to maximize birthrates, something that is no longer a good. A woman whose fertility is controlled by a man bears more children, statistically, than one who controls her own. In the agrarian age, especially its earlier millennia, maximum population growth was required. Neighbors were often hostile. You needed the numbers to win the wars that were a constant fact of life.
But the subordination of women, however much it was required by the need for high birthrates, and however much a virtue of this necessity religious teaching made it, was not, in itself, a good thing. It was horrid. And so, as the industrial revolution changed our material circumstances and maximum birthrates became a liability instead of an asset, it was changed as soon as could be politically and culturally arranged.
Free women, women in control of their own fertility, conflicts with traditional Christian morality (and Muslim morality, and Hindu morality, and Jewish morality, and so on) on all matters of sex, reproduction, and the relations between genders, not just on abortion rights. The conflict over abortion rights is only a part of that larger conflict, which will endure until the "great" religions change to accommodate the times and the new reality.
