You know how i know rape culture is a thing? Because a staggering percentage of teenage boys do not know what rape is. They think 'no' is an invitation to try harder. Because married women are not told that they CAN say no to their husbands. Because we tell teenage boys that they are not responsible for their thoughts or actions if their fellow students wear shorts that are too short, or because their bra strap is visible.
We need to acknowledge that there is a problem, and understand that our sons cannot learn about respecting women and their right to say not if we don't talk to them about it.
