Even today impartial discussions around the noble ancient Greek concept of euthanasia are hardly possible in German speaking countries. The concept of euthanasia is still tainted because of Germany’s Nazi past and the perversion of the concept by the Nazis.
At first glance the same seems to go for the concept of antinatalism. Before the concept of antinatalism was used in order to designate a moral theory it had been used by such thinkers as German historian Gisela Bock in her contribution ANTINATALISM, MATERNITY AND PATERNITY IN NATIONAL SOCIALIST RACISM (1994). In her text Bock scrutinises Nazi antinatalism as being directed first and foremost against women and especially women of Jewish and “Gipsy” origin, many of whom became sterilized. Bock even draws a line from antinatalism to euthanasia and genocide. Against this background the concept of antinatalism looks tainted and it wouldn’t recommend itself as a name for a humane moral theory.
However, there is a second usage of the concept of antinatalism – prior to designating a moral theory. It is in the domain of research on development policies from the 1970s and 1980s where we find the concept of antinatalism being used in order to discuss such topics as an antinatalistic population policy in a series of developing countries (see e.g. Christian Oswald, Familienplanung als volkswirtschaftliches Investitionsproblem, 1979).
At a second glance it looks like the concept of antinatalism first appeared in research on more recent population policies. And only later was it used in order to reflect on earlier Nazi population policies.
While this suggestion needs confirmation by further research it seems probable that one cannot reasonably consider the concept of antinatalism as a tainted one.
