Take the following as truth: Thirty years may seem like a long time to someone nursing a grievance since the pitched battles of the late '60s, but in the sweep of history--on the heels of 90 years of Jim Crow and 200 of race slavery--it's nothing.
Then the following statement: "30 years is an extraordinarily long time for a civil rights marcher, even in the grand scope of history." is true, false, or inconclusive?
