If sexual assault always affects trust, then #AllWomen are walking around with PTSD and trust issues. I for one don't let THE MANY MANY TIMES I have been sexually assaulted and various other crimes (I do live in South Africa) be a guiding factor of my life. I have consciously chosen to trust on purpose. However, only insane people close their eyes while trusting. I don't shy away from trusting, I just make sure that I let people tell me who they are, and then I LISTEN and respond.
You would be horrified, but I am not. I am NORMALIZED to this level of violence. It's natural. More sheltered people in my country have no clue what it's like to be a fully-engaged and person-on-the-street. You get used to it. Like children in war. It's the thing happening now and then that adds an anomalous punctuation to your life. You can't spend every day crying. The country is economically stuffed so you have to get on with making money, to eat. It makes you more articulate about the violence processes and nuances. More than sheltered people. And in my case, I articulate publicly. Some articulate in other ways.
