1. During the Holocaust, the differences between people became matters of life and death. Religion was the most obvious one, with Jewish people being at a particular disadvantage. Ethnicity, sexual orientation, age and income all played a significant role in the Holocaust.
2. Differences between people do not always lead to conflict. Many of the most peaceful countries nowadays are very multicultural, such as Canada. If differences are seen as strengths, and not as weaknesses, countries with great diversity can be very peaceful.
3. The Holocaust can serve as a lesson on how humans can get so caught up in differences that they behave in horrifying ways. If people looked towards similarities instead, conflict could be avoided.
4. It is very important to remember what took place during the Holocaust so that we learn of this mistakes and ensure that the world does not act in such cruel ways again. Although we have not been able to prevent tragedies altogether, keeping the memory alive will hopefully help us reduce their occurrence.
5. People who lives through these events might want to forget because they are ashamed, or because the memory is too painful. People who did not experience it might forget because they were not affected by it.
6. People might want to remember as a way to honour the victims. They might also want to remember in order to avoid repeating the same mistakes.
