But my male friend said - that the reason they are able to keep women down so well - is because women are so nasty and cruel to each other themselsves.
Even if this is true, (and I don't believe it is as black and white as this) surely you have to ask yourself WHY women might be so nasty? What have we been taught? I read a fascinating article a while back that made the point, very eloquently, that IF women are bitchy in work place etc, it's at least partly because they look around and realise very quickly that a) to survive in a man's world they have to be even more "manly? than the actual men and b) there are only very very limited spots at the top for women so if you want your spot, you have to make sure that you are the only women available so that when they're filling their "female" spot, you're the one who gets it.
And who created that system? Who made it so that firms get one female manager in a senior position and immediately stop making any effort because "see, we've got women here"
Who created the system that made it so that if women back each other up they ALL get tarred with a particular brush and suffer accordingly?
Someone once pointed out to me that the old boys network is interesting. Because if a man recommends his old uni buddy's son for a job, for example, and said son turns out to be a waste of space what happens is either no one wants to acknowledge it for fear of angering/alienating the man who made the original recommendation and/or the person who made the recommendation is not blamed for the poor performance.
But this does NOT happen with women. If a women recommends someone for something and that person does not live up to expectations, the original women's reputation is likely to suffer.
But of course, it's all because women aren't supportive of each other.
WHoever's male friend came up with this should probably take a closer look at that friend. There are lots of men like this, supposedly supportive of feminism etc while very quickly making it clear that WOMEN need to change how they behave, not men.
