Let me suggest that on this particular issue you are projecting the SWP's odd obsession with "proving" that working class men in no way benefit from the oppression of women onto the wider socialist left, when it is in fact a unique quirk. And that in a more general sense you are adopting a tendentious variant of a radfem analysis of the Marxist left.
Um no, the socialist party really do have a similar view about that, and the CPGB too, probably others. Tendentiousness in feminism just means you're doing it right. And especially if it comes to rape and assault, sorry to be so tendentious as to disapprove. Most feminists would and do disapprove of the rape apologism demonstrated by the SWP- scorn for that is mainstream in feminism now.
