I don't understand what the question means tbh.
What is this "it's equal"?
It's not equal, it's not not equal, it's just all wrong.
I don't want my DS beaten up either.
But it's simply meaningless to say: "would you rather your daughter was in a DV relationship where she was beaten up once a month or your son was mugged and beaten up on his way home from the pub one night?"
It's just silly. Nobody wants either, do they?
And of course it's equally wrong to beat someone up if they have a penis, or if they have a vagina.
Talking about being mugged on the way home as if it is the same as DV and involves the same dynamics and interactions, is meaningless though and I don't really know what the point is.
