At this point inevitably the scapegoating begins. Everyone has something they dislike, and the "naturally good" folks invariably pick out some institution or group of people that they demonize as this "source of all evil." Dawkins blames the Christians, others have blamed the Jews, or blacks, or capitalists, etc. From here it is a short walk to the natural conclusion: Utopia could be ours, if we just stamp out the Source of All Evil that is corrupting society!
And so a nice-sounding belief that everyone is naturally good becomes, by ruthless logic, a driver of genocide against the scapegoated group. You can see this again and again through history. Such a nice-sounding idea. Such hellish consequences. All because they won't acknowledge that sin begins in their own heart.
Should read “why then do we sin?” in the 2nd sentence, sorry.
Dawkins, or any atheist, doesn’t claim everyone is born ‘good’.
It may be the conclusion one who believes everyone is born ‘sinful’ might come to though.
