In a sense, the world as we have known it up until know, and continuing now only to a slightly lesser degree, runs on and depends on the aggressive nature of men. 'Inappropriate' violence in the home or on the street is considered as collateral damage. But we're not supposed to say this.
I would like to see a world in which male tendencies to aggression are curbed from the start. That all boys are discouraged from 'rough and tumble', that every boy is educated about violent behaviour, not just the odd talk once a year, but as a weekly part of the school curriculum, through every year, tailored age appropriately.
In other words, put an enormous effort into stopping male violence before it becomes ingrained, before the testosterone kicks in, before the feelings of privilige and superiority kick in.
That we fund massive and ongoing advertising campaigns against all forms of violence, led by all those men out there that defensively say 'well it's not me, don't blame me' when subjects such as rape and DV arise. Just read the comments on the DMail or CiF. Fronted by the David Beckhams, Kanye Wests of this world, as basically the majority of y oung men don't listen to women.
We have failed with sticking plasters on afterwards, with ineffective policing, prison sentences, slap wrist courses for offenders - for some woman or man it's too late by then.
Tackle the problem at its roots.
