It’s not me, it’s you: One origin of hate
When awful things happen, we are left wondering how and why such a thing could happen. How could one human maintain such ignorant and hateful beliefs about another group of humans? How could one human hate so intensely that he would sacrifice his freedom, his life, in order to destroy the lives of others?
When a person feels disadvantaged in some way, there is a tendency to resist accepting personal responsibility for that disadvantage. If I can blame others for my situation then there is nothing wrong with me, and therefore, there is no need for me to change. But there is reason for me to be angry. If I have been told, as my father was told, and his father was told, that my problems are because of a particular group of people, then those people become my enemies. If I believe that there aren’t enough resources for us all, then I must hate and destroy you in order to ensure my survival. And, in order to protect this set of beliefs, which has been passed down for generations, I must ignore any information that goes against my beliefs. Those ideas that conflict with my own are lies, made up by my enemy, designed to make me look foolish.
Generational ignorance and blaming of others, the belief in the scarcity of resources, psychological dysfunction, and fear all play a part in creating and maintaining hate. And it is very hard to change the mind of the irrationally committed, which makes this type of hate especially scary.
