Abstract: Feminist research into the position and participation of women in contemporary fundamentalist and traditionalist identity movements shows how essentialist ideologies of sexual difference are often deployed in critique of western secular liberal feminism. In this article the author draws a comparison between discourses of belonging according to studies of ba'alot teshuvahin the USA (female “returnees” to an Orthodox Jewish lifestyle), and her own interviews with “frumfrom birth” women (raised as haredi) in the strictly Orthodox Jewish community of Antwerp, Belgium. Whereas for the former, a rhetoric of choice, essentialism, and religious ideologies of female superiority appeared important, for the frum-born women, gender is more a question of orthopraxis and religious role equivalence. Nevertheless, the author argues that for the strictly Orthodox Jewish diasporic community in question, an increase in gender conservatism, with particular notions of female sexuality and modesty, goes hand in hand with isolationism vis-à-vis the surrounding secular society.
