Harav Eliyahu: The Emmanuel Rozen Story Proves Women Shouldn't Serve In The IDF

What exactly is the logic here? Harav Eliyahu's basic argument is that sexual harassment is endemic in society, and as such we shouldn't be allowing women to serve together with men. Fair enough. However the same logic can only really lead to a completely segregated society - something that is non existent even in the Haredi community. Moreover, considering by the amount of sexual scandals that we keep hearing about in Haredi communities, it would seem that the same logic would demand that we all send our female daughters to live their lives in closed nunneries, preferably somewhere in Siberia.
