Atheism and terrorism
There has been a connection between Atheism and terrorism over history.
Robert Pape of the University of Chicago points out that the Tamil Tigers, a Sri Lankan terrorist group responsible for more suicide bombings over the last two decades than even Al Quaeda, are heavily influenced by an atheistic Marxist/Leninist ideology. Many atheist despots of the 20th century, namely Joseph Stalin and Mao Zedong, committed terrorist acts in their attempt to create a religion-free utopia. Those three atheists alone murdered more than 100 million people.
