It never was about the science, and the science will never convince those who want to force births. It isn't even just that the cruelty is the point, but it's about conserving "traditional values" of women at home completely occupied with having and raising children and serving their husbands, not existing alongside them in the world, in service of the patriarchy which in turn serves capitalism (more kids = more workers, women at home doing all that unpaid work..).
