This is really interesting points and I am very supportive of the MARC work so I want to understand more. Could you expand on how the biology message could hurt the work ?
In terms of healthcare that translates into usable tools .... I talk to folks about the 3 core skills folks who've have experienced trauma need (self-regulation, positive self-identity, and co-regulation - relationship skills) and then break those down into core wellness skills that can be practiced each day individually, as families and adults, as well as skills that we want all organizations in communities to practice in their workforce and with their clients so that we build overall community health. There are very concrete skills in these areas like mindfulness, shame resilience skills (work of Brene Brown), and interpersonal effectiveness skills like from DBT.
Hope le that helps
