A movement which splits the working class (proletariat) on gender basis (i.e do you belong to the offspring bearing gender, or to the non offspring bearing gender?)
I would have thought that distinction was obvious, but then not all of us went to Orpington College in 1976.
I thought they taught A levels at Orpers in those* days, to mixed classes?
(Marxist roots of feminism was taught in A level Sociology, maybe still is. There's plenty about feminism and Marxism on the internet.
The class angle as far as I can see is a delusion of your own concoction.
I've been trying to get my head around that too. One obvious uniting factor for women of every 'class' is that all have faced discrimination on the grounds of their sex but so what? Strikes me you may be a bit hung up about class, sorry if I have misjudged you.
HWB:- "...deliberately appointing only females as dental hygienists/ admin assistants/ secretaries/receptionists"
News to me (as an ex HR manager) there was any deliberation about it. Not many men applied for those jobs except admin assistant. Secretaries are now executive assistants or some other title and whilst there may be more women than men, there are men who do such jobs, appointed because of suitability and not sex. There are male receptionists and male veterinary nurses just as there are women who drive delivery vans and buses.
*or 'them' if you prefer.
