You're picking data to suit your beliefs. Another of your own sources said the number was 40%. In any case, this contradicts your prior claim that: "There is absolutely no historical connection between religion and war." That's quite false, however you cut it.

I can't possibly exaggerate the dangers of religion in a country that (because of religious belief) rejects science and critical thinking, murders health workers, and tries to force Creationism into public school classrooms as though it's science.
And what benefits did you have in mind? A way to control the behavior of people who aren't very smart and need to have their hand held as they cross the busy street of life?
