Badly written and a misrepresentation of Murray's point to boot. Talk about building up a strawman!
As for the assumption that all of us here presuppose that women share all of their experiences - I think that is a misunderstanding of the feminist argument. Which is that:
Not all women experience all of the things that arise from having a female body and from being born female in a male-dominated world, but all of those who experience these things are women.
That's why they are called women's experiences - because only women qua females have them.
Thankfully not all of us suffer male violence, but the vast majority of us fear it because we have either experienced it ourselves or know someone who has.
95 to 97% of us menstruate at some point during our lives and those who do not will have medical investigations to find out why. That makes menstruation pretty much a near universal female experience.
80% of us become mothers. No idea what percentage become carers, but I do know that women are four times as likely to adjust their working hours to take care of someone at home. Don't know what the overlap is between these groups, but it is highly likely that not all carers have children themselves.
So, given the amount of caring work women do - whether that is looking after children or parents or partners - the sacrifices women make to take care of others can also be considered a near universal experience.
And according to official statistics, 70% of us experience sexual harassment and 40% male sexual or physical violence (the extent of how these two groups overlap is again unknown). But 80% of serious sexual assaults and rapes go unreported, so who knows how high the number of affected women really is.
So while not all women experience male violence and not all who do experience the same and are effected to the same extent, again we can say that so many females experience unwanted attention and/or unwanted touching coming from males that it is a near universal experience, too.
And so on. What combination of these things an individual woman experiences we obviously can't know, but we can make a few reasonable assumptions as to how widespread they are and therefore how much of a problem.
That doesn't mean that all women's lives are effected to the same extent, and not all women are disadvantaged to the same extent but a large number of us are disadvantaged, discriminated against or oppressed at some point in our lives and we also know many other women who are effected even worse than us.
Nobody is forcing anybody into a sisterhood or assuming it must exist - I avoided all things with even a whiff of sisterhood for all of my life and didn't experience anything remotely like it until 17 months ago. Nobody cared. Not even me.
But I have realised that I cut myself off from a source of incredible strength and support and love. Yes, it's not all been kittens and roses, but what in life is? I've realised that I would rather have this sisterhood, warts and all, than not. And that's a decision we all have to - and can - make for ourselves.
