Why atheism always has a burden of proof

[Polaris]

A book criticized for having, and I quote, "a casual approach to basic research," and has been accused of manipulating sources to reach false conclusions. Wow. Rolleyes

Incidentally, would you be kind enough to point out the parts of this book that cite atheism as a cause for genocide? Some quotes, maybe?

The book does not because it's absolutely fucking retarded to blame atheism for anything. Oh and if you're going to pull the first result off Google as you have been doing, try and make it look like you did not do so. Laziness should be left to the Christians.
