We also saw this in social therapy and Rojzman wrote a book called "how to avoid violence thanks to conflict".
Actually he disagree with the extension of the word conflict to violence.
We need places and ways to express conflict more and better and more safely! Of
course, in that case, conflict just mean you disagree and oppose views. Personaly I just want my view to be seen and see the other's.
A big piece we saw to avoid escalating from conflict to violence was to be true, even already to oneself, about our possible responsability. If there is safety to express it, it can lower the emotional level.
Then being personal enough to keep seeing we are humans!
