Publish norms like "criticize ideas, not people," "assume good intent, test for impact," and "step up, step back." Ask volunteers to paraphrase opposing views before replying. These practices transform heat into light, making conflict informative instead of exhausting or alienating.

Trauma-informed guidelines prevent compounding harm and demonstrate that learning never outranks the wellbeing of people doing the learning.
