Isolated, mixed-sex social groups of unpaired individuals are inherently unstable.
We can improve stability by decreasing isolation — via external accountability and communication, surfacing problems to external authority with the power to act.
We can also improve stability by maintaining stricter single-sex spaces: separate, sex-segregated living quarters and facilities. It shouldn’t even be possible for an outlier abusive man to make his way to a woman’s door, after hours and without permission.
Both cost more, but that should be factored into the cost of putting humans through unnatural experiences like this.
