Reply #4: Because of human nature

[Az]

We learn by observing others and copying their actions and ideas. When we want to educate others (and we do) we seek them out and try to exchange our way of thinking with them via dialog and demonstration. There are social taboos against doing so uninvited. But sometimes the urgency of one's position overrides such social barriers and they attempt to impose their views out of a sense of need and a belief that there is some information that the other does not have. Sometimes the reaction to this crossing of boundaries can result in anger and resentment from the recipient and this causes an escalation of anger and attempts to force ideas onto one another. At this point however the ability to internalize the concepts of the other becomes occluded and the focus shifts from ideas to emotions and that leads to aggression and attempts to harm one another in order to return the sense of anger and frustration that one feels from such situations.
