It's still that way, no matter how you present. If you're a woman, good luck getting justice after going through the horror of an exam and a police report in which you have to relive that same experience and a trial in which you often have to face your assailant directly, reliving it yet again. If you're a man, good luck even having your initial report recorded in the official record and then receiving no support in dealing with the trauma and violation and then risk being outed and treated like you're a weak subhuman if you dare try to reach out for help. It's one hell of a sick joke all around.
Believe everyone when they say that they were assaulted, full stop. Everyone is entitled to compassion and care. In terms of making sure no one else is assaulted by the same person who assaulted them again? Collect all evidence, with all care, every single time, process it in a speedy manor and let the usual standards of criminal justice apply, as they always must. Anything less is a direct menace to society.
