Until then, I content myself with publicly shaming them. Women depend upon conformity more than men do. Men are more comfortable going against the crowd. Women simply aren't. Women don't do anything if they're not convinced they'll be accepted afterward.
Race-mixing is especially potent (A) because being publicly shamed for having half-brown kinky-head black babies is so devastating to the target and (B) a very powerful cautionary tale to other female witnesses. The target can't un-have half-brown kinky-head black babies. She's stuck with her decision forever. Her shame is permanent (as it should be).
But other women are apt to see what she's going through and demand marriage-uniformity for themselves.
