Nobody has ever killed for atheism.<quoted text>
You are big on "evidence", as with your claim that dinosaurs had no DNA.
--The historical record of killing for atheism is 182,716 times worse on an annual basis than Christianity's worst year.
--There is a 58 percent chance that an atheist leader will murder a noticeable percentage of the population over which he rules.
--Atheist crime against humanity is 18.3 million percent worse than the very worst depredation committed by Christians, even though atheists have had less than one-twentieth the number of opportunities with which to commit them.
Hope that helps.
