I think fear and ignorance can become strong dark forces. What I try to do is to remember a newborn child when I am being challenged by the actions of someone. A newborn child is loving and trusting-his/her heart is naturally optimistic and good natured. Therefore, to me, a human being is naturally inclined to be loving and altruistic.
As time moves on, I think the balance between contructiveness to destructiveness is 3:2. This gives me hope about humanity. Just care about one another. Dont look for or focus on what you are against. Realize what you are FOR. And spend time with others that share your FOR.
