"A new survey of Americans' knowledge of religion found that atheists, agnostics, Jews and Mormons outperformed Protestants and Roman Catholics in answering questions about major religions, while many respondents could not correctly give the most basic tenets of their own faiths."
"Forty-five percent of Roman Catholics who participated in the study didn't know that, according to church teaching, the bread and wine used in Holy Communion is not just a symbol, but becomes the body and blood of Christ."
"More than half of Protestants could not identify Martin Luther as the person who inspired the Protestant Reformation."
I would say its biased..Why? Because of course Atheists will know more about religion than any other group. It is because they are Atheists. =P
I just find all this stuff fascinating since a nation's collective psyche is mildly amusing...although very quite sad.
Take the test and see how you do.
