Beachcomber - First of all your misinterpreting who is arguing those points, I'm not telling middle age white feminists to STFU, I'm highlighting the arguments that are used by sister advocates of the social justice movement (LGBT, race advocates etc). Personally I find trying to silence someone based on their ethnicity or class to be crass, bigoted and authoritarian.
But I'd be lying if there wasn't some level of irony in the fact that the weapons of war that middle aged, middle class feminists used against men and anti feminists are been turned on them.
Secondly domestic and sexual violence is not a gendered topic. In the US men are more likely to be raped if you are including prison rape into the statistics (which you should since it would be horrible to consider prison rape as a 'less than' crime). I wouldn't be particularly surprised if the patten was similar in the UK.
With domestic violence research does indicate women are a significant majority of DV victims (although with each study the percentage of male victims does seem to be rising quite fast) the truth is we are unlikely to be getting 'true' results, no statistical study is perfect but with DV in particular cases of male victims are going to be underreported for the following reasons; men aren't aware of what constitutes female on male DV, even if they are they are voluntarily not going to recognise themselves as victims due to immense social stigma attached to it, and even if they do they aren't going to report it to the authorities as they (quite rightly in my opinion) perceive the current DV system to be anti men...for example there are a few cases of male victims been arrested due to the use of the Duluth feminist model and mandatory arrest policies in use with police forces and prosecutors across the world including the UK. This powerful social stigma prevent a lot of male victims of female violence from even self recognition of it nevermind admitting it to a researcher.
Ultimately these are issues which are far from exclusively suffered by both middle aged middle class women and women in general.
Also class as in economic class (as opposed to sociological class) refers to income. I'd classify class politics as more class warfare as opposed to identity politics which focuses around social as opposed to economic issues.
