This is also why people have been saying since the '60s "Young people are less racist and more progressive! As the older generation passes on, things will get better!" A comforting idea.
But you can see from looking at the demographic graph, and seeing the way that White Americans of all ages vote, why this predicted "shift to enlightenment" didn't happen in the '70s, '80s, '90s, 2000s, 2010s, and it won't happen in the 2020s.
Unless we change it.
