Although this sort of thing isn’t just a war on choices for women, it’s a war on women in general. After all, no fault divorces noticeably reduced women’s suicide rate, their murder rate…
You’re thinking too small here - it’s not that they’re only trying to get rid of no-fault divorce, it’s part of a larger agenda to enact a bunch of changes to get society back to the point where men could fully control women’s lives. E.g. a man could beat his wife or child until they required hospitalization and that was a “private matter” not a criminal one, or have his wife institutionalized purely on his say-so. The situation before no-fault divorce benefited men more than women to begin with, and the return to that will include a bunch of “outs” and loopholes that are intended for men.
