This has been somewhat complicated by the simplistic idea that white people and black people are homogenous and want the same thing. They aren't and they don't.
The proliferation of social media means that there is no clear definition of what racism is, or what is or is not racist. Instead, this is asserted on an individual basis by people interpreting reality in their own way. At first this wasn't a problem, but we're getting to the stage where even well intended actions of anti-racism are labelled as racist.
When put into a No-Win situation, most people simply stop trying. - it's learned helplessness. The apathy that you have described so well here is possibly not just a product of race - it is also a product of a million mixed messages about 'how to be good'. The world continually fractions into ever smaller ideological circles each trying to assert their superiority to each other via the currency of suffering.
It's maladaptive and dysfunctional and has led to a cacophony of competing voices that have rendered much of the discussion meaningless. White people clocked out in their droves.. In a world where everything is racist, it logically follows that nothing is. Social media is doing more harm than good unless people can actually get face to face and stop trying to out-do each other and have meaningful discussion about how 'othering' works and strategies that can stop it.
Great article. Fundamentally disagree on the root cause of the issue you outlined. :o)
