In reality, both under Hitler and under Stalin, the heavy emphasis was made on woman's role as child-bearer at the detriment of active roles outside of the family (in contrast with the early period of Lenin-Trotsky). The Stalinist and post-Stalinist Soviet society was extremely male-dominated, women often doing hard, menial work, while virtually all managment on all levels (outisde of schools) were men.
Hitler had Gertrud Schltz-Klink and Magda Goebbels in positions of power; Stalin had no women in his government (Alexandra Kollontai, appointed by Lenin, remained an ambassador of low rank).
Hitler did not ban abortion until 1943; Stalin did prohibit abortion (and made divorces more difficult) in 1936 - and the ban lasted until 1955.
I don't think many people realize how socially conservative the Soviet regime had become under Stalin. Homosexuality was a felony punishable by 10 years in prison, for example (10 years in the Siberian gulag is pretty close to death penalty, in practical terms)
