So Atheists: Has your community made any serious contributions to world peace like theists Gandhi, MLK, Teresa?

I haven't seen any atheist Inquisitions or Crusades. Atheists don't seem to want to burn people at the stake or practice Jihad. They don't kill in the name of "nothing". Atheists are usually atheists because they think. They care about what influences the world. Whether or not they come up with the right conclusion doesn't really matter as long as they are intellectually honest. If they find God or, as in my case, God finds them, great. If not, they're fulfilling what God wants of them: using their intelligence.
