but a culture where speaking up is frowned upon encourages victims to hide their abuse.
It’s not. It’s a different part of the world with a different kind of conservatism.
I wrote and deleted an anecdote, point is - it’s not a Western atomized society, extended family and friends and various other social ties play a bigger role and all of those help the victim more than the abuser in such an event. Unless we are talking about some hopelessly poor village.
Frankly if those ties would work the same in Western “conservative” settings, those would probably improve over time.
