Classification/Symbolization

The first two stages of genocide are classification and symbolization. Both are very major stages in genocide, but they aren't necessarily a major issue in general.
Whether or not they are an issue really depends on how they're used. For example, the swastika, prior to WWII, was a positive symbol that meant good luck. However, during and after WWII, the swastika meant this negative idea of prejudice, hatred, and destruction. If a person in the US sees a swastika today, he or she immediately sees the idea of the Holocaust and pure hatred and prejudice. However, in India today, the positive idea of good luck is still represented by the swastika.
