If you choose to focus exclusively on the abstract you choose to live in a world where all of these conflicts are permanently laid out in stark contrast. The reason your mailman, for example, has no reason to have a problem with you is because he is focused on the practical and material reality of doing his job. The reason the speaker in the article was able to respond gently is because she has a working relationship with the journalist who interrupted her.

Minus the real ties people develop between each other, and the interest in having a comfortable environment around them, human history has more than enough wrongs documented to justify everyone's anger against everyone else.
