@taz What happened since then proves my point. "The moral arc of the universe is long" and all that.
Reform doesn't happen overnight. It has to be preceded with changing public opinion, which comes with increasing education. As ignorance falls, tolerance spreads.
We now live in the information age. Ignorance is no longer an immutable question of upbringing; it's a choice. Do some still choose the creature comforts of seeking information that reinforces their biases? Sure. Such is the human condition.
But more and more people seem to be seeking to educate themselves and seek real justice. And I believe that, as information continues to proliferate and expand, along with our increased free time due to automation, that widespread desire for self-improvement will only accelerate.
