Having led groups in various fields for nearly 40 years, I am concerned about many of the conversations on this website that devolve into shaming and personal attacks. Also, questions like "Should there be political comments allowed?" are beside the point, because political comments (like any other comment) can be relevant or irrelevant to the conversations. My recommendation to Ken and the leadership is to have three simple rules (norms) that are clear to all and easy to follow.
1) All comments need to be relevant to the posted topic
2) No personal (ad hominem) attacks. It is fine to criticize or vigorously disagree with another member's opinions, ideas, or comments--but not to insult the other DA member personally.
3) Cite your sources (improves credibility and discourages plagiarism)
