I still believe this is possible, I just think we're one or two generations behind. I'm encouraged that the coming generation seems to understand fairness and equality much more naturally and intuitively than my own generation.
Where I still feel like I need to be vigilant against racist thought creeping in (simply from conditioning, stereotypes... I don't consider myself racist, but it's so easy to become tribal without realizing it), for people just a few years younger than me it seems it's just that much easier for them. And the next generation after will hopefully be better still. I have hope.
When you think about it, humanity went very quickly from largely homogenous, semi-isolated communities, to a global community, with lots of movement. It’s going a while for the system to equilibriate. And while there may be many little racist Maxwell’s demons running around doing damage in the short term, I have faith that in the long term we will get there.
