Your basic non-reflective atheist claims (without reason) that "religion is the cause of all evil." When asked to justify this few can answer, except to mention "the Crusades." When further asked about the Crusades few can say anything about them, to include being able to state when they happened. Yet they believe.
Little can be said to justify the atheistic claim against religion. Because, as Alvin Plantinga writes:
"Of course the world’s religions do indeed have much to repent; still (as has often been pointed out) the suffering, death, and havoc attributable to religious belief and practice pales into utter insignificance beside that due to the atheistic and secular ideologies of the twentieth century alone." (Plantinga, Where the Conflict Really Lies: Science, Religion, and Naturalism, K99)
