Sorry, but the evil Margaret Sanger (whom I have studied for years), was in her hay day in the 1920’s. One of her most famous speeches began with the line, “It is the right of every child to be wanted.”
then if that was a current phrase of that period I stand corrected...
“It is the right of every child to be wanted.”
In a better world, a safe assumption would be that every child would be matched with an adult that wanted them.
