Rule by force is the disease, who and how are symptoms.
As long as the majority remains silent while these people kill those people because reasons, we can expect to be ruled by the most violent on the block.

Peaceful coexistence is less possible while toleration of rule by force is the norm.
Silence does not necessarily mean to submit.
