Knowing and not knowing.
I think they do know how dangerous the world is for women. Ex:
Me and my brothers (12, 15) were about to play Xbox live, and me and my younger brother had never played before.
As we enter the Xbox live lobby, my older bro turns my mic off and he: “you can’t be on the mic.”
This shows me he does know a bit about the abuse that women face, but he would never admit that. Strange.
