I agree BenLinus, I've said the same previously - if TW face violence from men then that is awful, and wrong and an example of male entitlement and male violence. But the solution to that is to tackle that entrenched male violence not to come and demonstrate that same male entitlement by imposing on women's safe spaces.
Campaign for your own safe space, or campaign to make the space you have a safe one. But stop trying to make our safe spaces unsafe because right now we have (or are heading for) the worst of all worlds - sex segregation on the face of it which decent and respectful men will abide by, but segregation which is easily ignored and impossible to enforce and so will be abused by violent and aggressive men.
I would genuinely rather have full blown (appropriately designed) fully unisex facilities than that - at least then there would be more people going in and out and the presence of decent, non abusive men might actually offer some degree of protection. I appreciate all the arguments about abuse survivors and so on, and I'm not disputing any of those - just saying I would prefer actual unisex to bonkers dangerous half way house.
I think with the current state of affairs it is only a matter of time before we see quite large numbers of abusive men taking advantage of this unenforceability. I know it is already happening but I mean more widespread - at the moment not that many people are aware, relatively.
