If the world does come to an end here, or wherever, or if it limps into the future, decimated by the effects of religion-inspired nuclear terrorism, let’s remember what the real problem was. That we learned how to precipitate mass death before we got past the neurological disorder of wishing for it. That’s it. Grow up or die.
Theists often argue that religion promotes moral behavior because it promotes the belief that moral behavior is a prerequisite for entry to heaven. But then the focus isn't on this world, it is on the next world. And it isn't on one's own conscience, it is on what one perceives to be the doctrine of one's religion. In many cases, and in most cases through out history, prevailing religious doctrine has held that nonbelievers should be slaughtered and persecuted. This is still the practice and predominant doctrine in many of the world's poorer areas; and with the proliferation of nuclear weapons in precisely these areas, areas where Islam is used as a rallying cry for international full scale war, areas where blasphemy is a state crime punished with murder, we see an ever greater risk that nuclear weapons will wind up in the hands of those who act on this Earth with abandon because of perceived heavely rewards.
Likewise, in the US and across the Christian world, there are a great many people openly hoping for the "rapture", praying that the time will soon come when a global apocalypse will wipe out mankind. These people make up a significant and politically powerful minority, especially in the US.
In the religious worldview that holds belief and "moral" behavior to be prerequisites for salvation, it makes sense to crush dissent. After all, when someone preaches against your religion or commits adultery or some other victimless sin, by doing so they alter culture and win converts in ways that result in more people going to hell and fewer to heaven. As those places represent infinite paradise and pain, they can be logically used to justify any amount of evil on this Earth.
To what extent is religion therefore responsible for a global pandemic of irresponsibility and callousness when it comes to the real world?
