When a person sees someone or some group take actions that clearly violate the rights or well being of some other person or group, and despite this, does nothing and fails to speak out, they display, at a minimum, apathy to the harm and injustice that results or tacit support for the evil done and the harm caused.
Apathy or intentional ignorance of such violations of the rights of others or the harm and abuse of others is not a way to escape the blame for not resisting such evils.
This applies to abuse of minorities, bullying of the weak, violence against women or children and many daily acts of neglect or abuse that touches the lives of individuals, families or identifiable groups.
With freedom, safety and access to information comes the responsibility to speak out and act. When a person fails to do so, their excuses do not matter.
