Quote of the Day
Even if religion did no other harm in itself, its wanton and carefully nurtured divisiveness - its deliberate and cultivated pandering to humanity's natural tendency to favour in-groups and shun out-groups - would be enough to make it a significant force for evil in the world.
- Richard Dawkins "The God Delusion" (pg 293)
Might not make as much sense out of context, but it's basically saying that the "us vs them" tendency of humanity is exacerbated more by religion than by any other source of division.
