While I can see a value in women becoming less polite, as this will help them at least to get out of situations where men are depending on women's politeness to get what they want, it absolutely won't help in situations where a man is going to get what he wants no matter what - a lack of 'politeness' may just result in the woman being more badly injured/killed.
I agree with you but there are many situations where women can exercise power but it often needs to be co-ordinated and have a tactic behind it (using our dark sides!).
Take this dinner where all the men were groping the waitresses openly - if all the women there had collectively walked out and told the fat sweaty pigs to fuck off, then the outcomes would be different. Yes, the risk they didn't get paid would be there but there are laws against what is expected in the workplace and so an action of 140 women against the organisers to get paid would have been much more productive than an article in the FT.
And maybe next time....
What I am saying is that women are not currently equipped to deal with these situations in a tactical and 'fighty' way. Of course we are encouraged not to tackle the power structures (with this constant theme of the lack of agency of women etc), but that's what I mean about our dark sides - men won't just give up this power. Being nice doesn't work.
