Even today there exist disivions between groups of people that are exploited for nefarious purposes. We have learned to hold up our own societies at the expense of others, to see outsiders as ‘others’ and less than. Colonizers created divisions where none existed just to subdue a population with almost unstoppable multi-generational consequences.
Education is the first solution. People must learn their own histories and reclaim their original stories from the colonizers.
Next we must teach all youth about Genocide. They must learn to recognize the pattern of behaviour and not hestiate to interfere with the process.
We must never forget the millions of human lives lost.
