- Don't join giant group chats unless you're Whiskey Pete inviting journalists into a "clean" opsec group.

- Know others very personally or not at all.

- New people can potentially be liabilities such as crazy, stupid, undercover cops or adversaries, and/or destructive without a care.

- Avoid people who think violence is "the way" because there's rarely a positive or politically-acceptable offramp for it.

- Destruction of property can be effective non-violent resistance in limited circumstances, e.g., The Boston Tea Party, but that's becoming a criminal in the eyes of the current regime and 95% of rebellions fail.
