If you're going to go to the trouble, compare that to the atrocities committed in the name of atheism. You'll never get close to the 100 million or more that have been eradicated just because the bad guys wanted to.
You're right, some people use religion as their excuse to do evil. Some don't. The appropriate conclusion is that people are inclinde to evil, not that the excuses they use force them to be.
Shalom.
You have to remember to list the number of people saved and spared in the name of religion as opposed to atheism.
Many people are not interested in "appropriate conclusions".
They're going to believe what they want to, and wave their tiny little fist at their creator.
Unlike the god of Islam, however, the true God does not need us to have His back. He isn't threatened by their ingratitude/defiance.
