The day will come when the barbaric practice of abortion will face history. It will not be kind. At least the Spartan society allowed a child to be born before determining if it was ‘weak’ and then left outside in the elements to die.
Relating to this thread, each farming family would usually have many children in the hope that some will live through childhood to become adults. Kids had a harder time in the long crossings as well, often dying first. Our success in reducing infant mortality along with the move out of the farming life has reduced the need to have so many children. Killing them in the womb has become preferable (and legal) to being ‘burdened’ with their care and support. Throw in many other societal and family changes over the years and those that came over on these crossings wouldn’t recognize or accept what we’ve become.
