In Western culture, self-confidence is connected with the ability to meet criticism calmly and to respond rationally. We are raised to see people who easily get angry when criticized, as insecure and immature.
In Muslim culture it is the opposite; it is honorable to respond aggressively and to engage in a physical fight in order to scare or force critics to withdraw, even if this results in a prison sentence or even death. They see non-aggressive responses to such threats and violence as a sign of a vulnerability that is to be exploited. They do not interpret a peaceful response as an invitation to enter into a dialogue, diplomacy, intellectual debate, compromise or peaceful coexistence but the opposite.
