For starters, I'm keenly aware of the disgustingly discrimination against women, especially in the old days - for example, in my home country of Portugal back in the 60s women weren't allowed to leave the country without authorization from their husbands, very much a "we own you" disgusting level of discrimination - but also in modern days the cultural, legal and economic factors that transform childbirth into a massive torpedo to women's careers and the main reason in modern days for the clear chasm in income that appears at around the mid-30s between highly educated men and women.

Further, I'm involved in a leftwing party in my country and the "gimme shit" discourse imported from Anglo-Saxon countries is sadly quite common amongst self-identified "Feminists" (mind you, that's far from the only self-defined group demanding to be given things not given to others - "greed is good" seems to have been interiorised by a whole generation that grew up in the last 4 decades and who think personal upside maximization disguised as "compensation for a group of people identified by things they were born with were otherwise completelly different people than me were discriminated against" is being "Leftwing" because they're not directly demanding it for themselves), though it's not the dominant one.

Having lived in that country for over a decade and having also been involved in Politics there, I've also seen a lot of that amongst the upper middle classes in Britain around the ages of 30 and below, were it comes from the various flavour of liberals (who are invariably neoliberals, as Britain currently has no real leftwing beyond the Green Party) who again think they're Leftwing so long as their "gimme" is voice as "give us".

Meanwhile I've met older Feminists and they're a whole different breed, not to mention women that fought for a better life for all, their whole lives, without ever holding the "Feminist" flag (my country has quite the Leftwing tradition and that was as much women as men).

Sadly it's got to a point were somebody loudly claiming to be Feminist is almost invariably a "gimme shit" person that's probably doing more to damage the broader cause of Equality that the much larger mass of Women out there fighting for equal treatment: as I said, what I believe is genuine Feminism is the "get out of the way and let me be all that I can be" kind - capable people who are discriminated against for being women rather than social players who are not against the system being gamed, they just want it to be gamed in their favour.

Mind you, the subversion of the Fight for Equality into competing groups defined by characteristics people were born with (the very same kind of way of reducing people to categories and then generalizing that anchors far right thinking) dominated by people driven by personal upside maximization is not at all specific of the fight for Equality for Women but a far broader phenomenon of subversion of the Modern Left through Divide et Impera techniques.
