Not only are 1 in 4 (!!) women domestically abused, there is also a connection between domestic abuse and other serious health problems. I know that doesn't prove causality, but it's still one of those strikingly high statistics (like rape statistics) that make everyone squirm.
For me, these are challenging things to hear. On one hand, this is information that clearly reveals that something is rotten with the state of women. But because these statistics are talking about such a specific problem, people think you just have to drive down these rates and sexism will become a thing of the past.
I think 2nd Wavers say domestic abuse laws should be changed - that will help challenge sexism. 3rd wavers would claim sexism causes domestic abuse, and you have to change stereotypes of women in order to effectively challenge domestic abuse.
But, I frankly don't have enough of a background to make those kinds of claims, anyone know a little more about the differences between 2nd and 3rd wave feminism?
