I don't have to really be in the 60s. Every time I hail a cab in New York, and they pass me by and pick up the white person, then I get a dose of it. Or when they don't want to take you to Harlem. I grew up with that.
It is not enough to understand, or to see clearly. The future will be shaped in the arena of human activity, by those willing to commit their minds and their bodies to the task.
