What ways does the community of Waknuk represent weakness in the novel The Chrysalids?

Waknuk represents weakness because its peace can be destroyed so easily. Instead of maintaining cohesion through change, it rejects change completely, and even minor deviations threaten the community. The deviations, symbolically and literally, control them because they react to them without stopping to think about it or decide whether the change is good or bad. A strong community would be able to adapt to differences, and maintain cohesion.
