There is currently a firefight raging between religionists and the "New Atheists". The New Atheists are blaming religion for taking a large death toll from the crusades to Islamic terrorism of today. While the religionists agree that religion is in fact responsible for a deadly death toll, they quickly point out that it is the godless communist regimes that are responsible for most of the bloodshed that has ever plagued mankind. The religionists also proclaim that religions responsibility is minuscule in comparison to the slaughter of over 100 million by the atheistic regimes of the 20th century. So he contends it is obvious that "Atheism, not religion, is responsible for the mass murders of history." The New Atheists seem to be fighting a quickly losing argument.
The irony of the whole thing is that if the New Atheists had any proper grounding in philosophy, they would have blown away the religionists a long time ago. Greg Perkins blogs about the rational philosophical necessity of atheism and explains what atheism is and isn't in the Objective perspective. The post can be found here.
It's an awesome read and great food for thought.
