I think there's a lot to that! Bouncing off your post Luce:

We internalize what was done to us/feel ashamed as the primary stigma, and then we experience our natural response (dissociation) as stigma too. Both are inherently survivor-blaming, but we're so invested in it because it's what we had to do to survive.
It's not just us though! It's also the perpetrators and bystanders (who perpetrate by refusing to intervene, acknowledge, or support us). It's a normal human response to trauma. Now that we know this though I want to see trauma-informed everything! Trauma-informed schooling, trauma-informed law enforcement, trauma-informed policy....
