Our collective good and common enemies

I believe that if good people would rise up against bad people we would have a better world. We tolerate evil because we are afraid but it should become apparent to us that fear will not prevent cru left from sprawling, blood seeping through the ground on our door steps. 

That's the central reason race, nations and societies remained in unfavorable circumstances like racism and slavery for centuries because people cannot assembly against their common enemies for the collective good of the group.
