I'm firmly in the nobody should be hitting anybody camp.
I read a study once (wish I could find that link again) that showed over 50% of the time the first violent contact in domestic abuse cases was from the female. You want to get in an endless argument bring this up in a mixed group. The study wasn't about who came off the worse, who felt threatened... it was solely about who crossed the line and hit first. But people are so ready to dismiss it because it doesn't fit the narrative of who the powerless victim is.
Whenever I see groups purporting to wanting to end DV, or to help DV victims but focused solely on one gender I figure they have zero chance of achieving that goal.
