Margeret Sanger was an American pioneer in Birth Control. The problem is, eugenics was the main theme at her birth control meetings. She spoke openly of the need to put an end to breeding by what she called “the unfit”. A quote by Margeret Sanger, ”...birth control is nothing more or less than the facilitation of the process of weeding out the unfit [and] of preventing the birth of defectives.”
So wouldn’t “Pregnancy Control” be a better term.
If everybody knew about the history of the term Birth Control (it seems a safe assumption that they do not) I suspect they would object to the term.
