For people of my generation, there was a narrative - not entirely spoken - that racism ended somewhere around 1968. That narrative, in turn, provided a foundation to the idea that attempts to correct for the effects of hundreds of years of racism were themselves racist — and, ironically, was allowed to suggest that problems that had their roots in racism were actually the results of the lesserness of other "cultures." The "end of racism" helped racism survive in dressed-up, yuppified form.
One ironic blessing of the Trump Era: Lots of folks don't feel the need to dress it up anymore. It's as out there as it's been in my lifetime.
