We Jews were liberated from Pharaoh's Egypt after an exile of 400 years. We Jews are commanded to remember this and tell it to our children as if we ourselves had been there too.
Liberation comes through faith and courage.
While myth implies storytelling and listening, taboo is the avoidance of what cannot be told or touched. Touching taboo is a not-permissible transgression leading to trauma, aggravation of forgotten trauma, or retraumatization. A modern Jewish and Israeli myth is that of the Warsaw Ghetto Fighters' Revolt in 1943. This was the terrible end of another Diaspora on foreign soil, which had also lasted for over 400 years. In the same time span, in November 1942, General Rommel was to overrun Egypt.
