Younger generations are exposed to international communities, daily. They don't dehumanize diverse cultures because they were raised in the globalization era.
Older generations live in isolated bubbles. They go to work, home, and visit family and friends. They rely on the mainstream media because it's familiar, and they do not encounter people outside of their social and income classes.
Humanity's shared emotions don't differ radically among age groups, but younger people freed themselves from nationalist constructs, realizing the world's interconnectedness. Their clarity and critical analysis are remarkable. THEY ASK QUESTIONS AND SEEK UNDERSTANDING. Imagine that!
