the fact that it happens is one thing - i agree that the authorities don't appear to be overly worried about it but that doesn't mean we shouldn't be pressuring them to do more to stop all rape in prisons.
One aspect of that is to stop literally enabling it by putting women - no matter how they identify, and especially when they are already undergoing a mental health crisis - into men's prisons and vice versa.
Or are you just "meh, shrug, it happens, get over it" (or that they should "reframe their trauma"? or that they deserve it?)
