Courtney Martin makes various questionable assumptions in this article, but her basic point is valid:
According to new research unveiled this month, women were far more involved in the atrocities committed during the Holocaust than previously thought. Wendy Lower, an American historian living in Munich, uncovered that thousands of German women ("a conservative estimate") willingly went out to the Nazi-occupied eastern territories to take part in the "war effort," otherwise known as genocide.
This news is disturbing, to be sure, but it's also not surprising. Anyone who reacts with shock to the reality that women have the capacity to be immoral, malicious, and violent -- just like the guys -- hasn't paid enough attention in history class, much less to the nightly news.
