Although the journal Social Text was never at the forefront of publishing articles on feminism and never debated whether capitalism was the source of womens oppression in 1970s or whether male supremacy was itself a systematic form of domination, it is not clear whether social feminists classification of the journal as the one run by boys club could have been completely justified till recently.
