For me, the biggest takeaway was the fact that there are so many conflicts (and people living under authoritarian regimes) that is in a way forgotten because mainstream media is not reporting on it anymore. However, these ongoing conflicts are driving millions of people to flight their home countries.
Also, a lot of these conflicts are rooted in devaluing people based on their beliefs, but also the people who are in power becomes obsessed with holding that power so they will do anything to keep it/protect it.
