Frak its fine. I think the OP has started this thread so people can ask questions.
The patriarchy is a short hand term for describing the way society oppresses women and gives a higher status to men. Through the law, institutions, government, culture, etc. So yes probably the same as what you mean by male centric.
Yes some men do suffer from DV. Although DV that leads to serious injuries, pate, death etc is almost always suffered by women. But the key point is that feminism is about focussing on the needs of women.
Individual men suffer from various crap situations. But under the patriarchy men get their needs looked at and cared about more already.
I think of it as going into a hall with an equal number of men and women. Some men are talking and men and women are listening to them. There are a few men struggling and some women are helping them. In a corner of the room are women who nobody is talking to. A few women are struggling, nobody is helping them. Feminism is about listening to and helping those women and girls that nobody is helping and nobody cares about.
That is why feminism - and I am talking about all kinds now - has prioritised working with women who have been raped, suffered DV, been sexually abused, etc. These area ll issues that are caused directly by the patriarchy and that most people didn't really care about until feminists started campaigning and setting up projects to support women.
