As a leader, as a boss, as a teacher, as a parent. You want people to challenge you. Not obey you. Dialogue brings engagement. After that, decisions can be made and an action plan followed. Otherwise what happens is that people simply block one another, and nothing moves.
An embarrassing incident at Stanford University highlights the importance of hearing challenging ideas.
Note: I would not include incitement to violence in the realm of challenging ideas. Rallies and publications which for example aim to “solve the Jewish question” or “eliminate the Jewish menace” are a way of generating mob violence, not promoting diversity of thought.
