The precedent that victims and survivors of abuse, whether racial, sexual, physical, by sexual preference, by gender identity, or of whatever sort, are met with disbelief when they tell their stories has throughout history supported the powerful and further disadvantaged the victims of power imbalances.
Whatever the "anti-woke" brigade might moan to the contrary, that pattern continues to this day.
When an individual comes forward with a report of being abused, the response is often to pick apart their credibility, and question their motivations. This happens even on these boards. For example, the Swedish accusers of Assange were written about appallingly. Regardless of how international actors may (or may not) have sought to use these allegations, the character of those making them were widely traduced.
This habitual doubt, incredulity and victim-blaming adds to the trauma of victims and survivors and makes it that much harder for others to come forward. People need to feel they are going to be believed.
Of course, the ingrained dualism of our culture is going to react by saying: that means you are automatically assuming the accused is guilty without any corroboration.
It does not. Believing the victim is not the end of the process. It is a corrective to automatically disbelieving them.
