Depends on what you mean by permissive. I think a more liberated society would be both less accepting of sexual violence but also less punitive towards it. As with other types of crime, a greater emphasis should be put on prevention, making the victim whole, and, whenever possible, rehabilitation of the offender.

In my view, our carceral based “justice” system has been an almost complete failure and needs to be redesigned from top to bottom. But this is an important issue that should be taken seriously, and if new systems don’t solve it effectively, then they might need further iteration.

my very tentative understanding of anarchy does not have good answers for women’s issues.

Anarchism doesn't have good answers for... literally anything. What anarchism does have is a better understanding of what things shouldn't be.

This might not be an anarchist issue,

It generally isn't... but the fact that a lot of anarchists I speak to don't seem to understand why it isn't an anarchist issue is. The answers to what an anarchist (or any kind of libertarian socialist) society should do about (insert given problem here) will not be found within the tradition of anarchist critique itself and the idea that they can isn't just hopelessly naive and utopian but , in my opinion, a self-destructive regression into orthodoxy.

The lesson here is: there is no anarchists cookbook; we all could learn from each other, but not copy algorithms and protocols. Know-how should be DIY, too.

Once someone refuses to think for themselves and adopts a method developed elsewhere without critical thinking, they are not free anymore. Once people start reusing old protocols instead of treating social stuff personally and on individual basis - they submit their power to a dumb machine that could and would be gamed in no time. This has nothing to do with gender or any particular form of violence.
