It seems as though a society that is intolerant of all forms of degeneracy shuts off its own Dynamic growth and becomes static. But a society that tolerates all forms of degeneracy degenerates. Either direction can be dangerous.... how do you tell the saviors from the degenerates? Particularly when they look alike, talk alike and break all the rules alike? Freedoms that save the saviors also save the degenerates and allow them to tear the whole society apart. But restrictions that stop the degenerates also stop the creative Dynamic forces of evolution.
