Well, since about 11% of the people on this Earth are non-religious, it is likely that they did not start many wars.
Who started WWI! It was a Muslim who murdered Archduke Franz Ferdinand of Austria! Who started the Crusades? The Muslims who had captured the Christian Holy Lands!
Are you reading challenged? What religion did Hitler practice? Stalin? Mao? Pol Pot? Some of our biggest murders where non-religious!<quoted text>
Do you even look at what you write?
You are arguing that non religious people start wars.
Just look at the muslims!
You are truly insane.
