De(a)thism is the modern philosophy that accepts policies and personal actions that lead to the death of other individuals. It is invisible like the water surrounding a fish.
A Dethist society excuses deaths that are the direct result of irresponsible behavior (such has intoxicated drivers or inadequate safety precautions). A Dethist society allows a small number of individuals to build massive wealth, yet it denies life-saving interventions for those who are unable to afford them. In addition, the training, accommodations and treatments that have a high priority of eliminating the need for such support are rejected in lieu of actions and policies that solely benefit the wealthy and powerful.
The Dethist society fears other persons because of differences in culture, appearance or means of communication. Protection against that other-ness excuses violence and destruction. A Dethist society is willing to discard individuals who have crossed the threshold of disability. A Dethist society supports political hypotheses, religious dogmas, and irreligious attitudes that emphasize other-ist divisions of the members from those who disagree. The lives of an "other" is denied value and consideration.
A Dethist will prefer to see a death as inconvenient rather than embracing those left behind as they mourn the loss.
