You're probably too young to   Recall what do US was like for women who became pregnant without wanting to be  before abortion became legal. For those who want to deny abortions two women who believe they need them;you might want to read about the thalidomide babies; mothers who had to raise children of rape even if they were unemployed;  or for those who need it abortions for medical reasons. Backdoor abortion butchers abounded. 
  If everyone wanting to make abortion illegal would simply donate one or $2000 a year for foster care and adoption, maybe we could solve the unwanted  birth issue -  though I guess all the other unwanted children would still be with us.
