Slaves  are sentient people , fetuses are not. Are you ready to forced donations of bone marrow, blood products  etc; in order to save a human life? That's  the same demand  when you force Women  to go tthrough an unplanned and unwanted  pregnancy. To be sure,  adoption does not solve the problem  because  the poster child (literally, in billboards  from Pro Life across  America) representing the ideal child to have available for adoption  are healthy  ARYAN infants. Seen this for  myself  in  Black and or Latino neighborhoods!
