Sorry I haven't answered people earlier. I am supposed to be working 
TeenaLena. You're referring to the US study. I'm referring to the UK study, where controls are in place. The trouble with the gender pay gap is that while it is illegal to pay a man more for the same job, it's hard to enforce. In the public sector or any industry where there are structured pay grades, it's a lot more transparent and easy to control. In the private sector it is a lot harder.
MarySue I don't see a contradiction between saying I believe a large proportion of men are violent while at the same time saying I like men. That would be a bit like saying because I got beaten up by one black person that I assume all black people are violent and therefore I don't like any of them. You have to treat each man (indeed each person) as an individual. And yes, I accept women can be violent too, but even allowing for underreporting due to embarrassment and shame I think there are far fewer female abusers. I think abuse is wrong full stop. I think stamping out abuse towards women far more effectively is actually the first step to getting woman-to-man abuse out there, talked about and also stamped out.
TheAtomic I don't know what the proportion of violent men is in society overall as we can only extrapolate on figures. I hope it's not as much as half, I really do, but 2 women a week killed at the hands of their partners suggests it's a not insignificant problem by any means. Does that mean that those who are not physically abused are happy? I don't know. I don't know anything about people's individual relationships, but the degree of family breakdown in this country combined with the fact that 70% of divorces (I think) are initiated by women, suggests that many marriages are not great, at least not according to the woman's perception. Again, that doesn't mean I think ALL marriages are doomed. Far from it.
The patriarchy is not a living breathing thing but it is something whose whole is bigger than the sum of its parts, and you don't have to be man who believes women are inferior to perpetuate it. The way it has evolved as our society has developed means that our cultural norms sometimes place perfectly ordinary, decent people under pressure to uphold it, such as reverting to traditional roles following the birth of a baby, which can result in a woman's equality being compromise unwittingly. For example, the woman has to give up work and become primary carer because paternity leave is not as good as maternity leave, and then, by the time she's ready to go back to work the man's job has progressed meaning he has greater earnings, which result in it being the mother's job that has to be forced to fit around childcare, compromising her earning potential still further.
