The dictionary definition of misogyny is dislike of, contempt for, or ingrained prejudice against women
My personal view is "handmaiden" gets used too often and is insulting. It is as useful as transphobe.
Way back on this thread someone said (I am paraphrasing) that a woman who thinks all housework etc is her responsibility to facilitate her husband's career can be described as a handmaiden. Whilst I do not use the term I disagree such a woman is a handmaiden. She is making a lifestyle choice which is not for me but unless this woman is in a position of power where she can influence social policy I think it has little impact on anyone other than herself. She might seek to influence her daughters but I would credit them with minds of their own.
On the other hand the Miley Cyruses and Nikci Minajs of this world seem to me to fit the definition perfectly. Rich, successful and powerful women choosing to collude with the objection of women's bodies to audiences of billions. And even if one were to buy the (weak) excuse that they had to go along with this to establish their careers (which I don't) they are both in a position to call the shots now. I still won't call them "handmaidens".
So I don't find it a useful term since "colluding with the patriarchy" means different things to different people.
Where will matters go? I think Scotland will race on with self-ID for gender status because (a) Westminster has put it on hold and the Scottish government will seize any chance to show how much more forward thinking and inclusive Holyrood is and (b) the Republic of Ireland already has this. (The SNP love comparing Scotland with ROI as a successful, small , independent state in the EU, except of course when the Irish tiger economy keels over)
The million women march seems a bit of a damp squib.
Men might finally get and understand the message that accessing porn on your workplace computer is wrong. Well obviously accessing it anywhere is wrong but how stupid to you have to be to use your employer's equipment.
