It's an interesting study. I don't think any of it will come as a surprise to feminists, though. But the more that this stuff is in the mainstream, the better.
There were a couple of bits that stood out to me. The first is the assumption that men who are more educated have better attitudes towards women. The study doesn't bear this out, which I thought was interesting. It's something I've long suspected. Certainly, better educated men can be more subtle about their attitudes towards women, and perhaps they move in circles where overt misogyny is less acceptable. But it makes me think of your lefty dudebro "feminist", who displays a surface enthusiasm for women's rights, but who has never analysed his male privilege, and who ditches the egalitarianism as soon as his position is threatened or questioned. I don't think sexism divides neatly along class, income, education or race lines at all.
The second is the assumption that not being married makes men behave worse. I find this quite worrying. Do men behave better because they have a woman at home to channel their disaffection onto? What are we saying here? That seems quite a disturbing message.
