I think that, when it comes to the US, it helps that a lot of this stuff happened fairly recently. I have a living relative who can remember sitting on the lap of her great uncle who had fought in the civil war. The Civil Rights fight happened in recent memory, and there are still scars left from that. And this all happened at a time when we were supposed to know better. In that sense, it's similar to the situation with Nazi regalia and the modern debate about fascist movements in Europe. We all got shit in our history that we have to contend with, and shit that happened in the last 150 years is still pretty fresh. Of course, we're still dealing with the leftovers of our racial history. This conversation came up again because of the recent church shooting, after all.
