Raising counter-examples shouldn't mean throwing shit at the wall to see what sticks, and the author's point could easily have been made without repeating an extraordinary claim he fails to provide evidence for. If The Body Keeps the Score had arguments as poorly sourced as "this textbook said that PTSD co-occurs with inflammation, so Western diets could cause inflammation which could cause PTSD", the author of the Substack would rightfully criticize it as unsubstantiated bullshit. His own article should be held to the same standards.
