The thing is women and girls DO modify their behaviour from as soon as they learn to walk and talk girls are taught to "be careful", to watch out, don't go out alone etc.
We are constantly told by many many different sources to be aware of where we walk, we watch our drinks, who we talk to, where we sit on a bus at night, we carry keys when we walk alone at night, we are aware of the dangers of rape, we get sold rape proof pants, and rape whistles, and mace/pepper spray etc. We inundated with "be careful" messages all of our lives. And still we are raped.
And if its not one women who is raped it will be her neighbour. Because rapists are out there. Their behaviour is both condemned and supported in our society. They are rarely arrested, let alone convicted and rape culture slaps them on the back and props them up, while selling women stuff to "protect" themselves with, and blaming women who don't follow all the "rules".
Women who live in countries where alcohol is prohibited get raped. Women who cover themselves with clothing from head to foot get raped. Women who largely confirm themselves to the home get raped.
Women who go out at night and get obliterated on alcohol get raped. Women who don't drink get raped.
So yeah victim blaming totally sucks. And it doesn't work. It's really fucking stupid.
