I suspect she knows exactly what she is doing, and her intent is to "normalize" such propaganda for the very reason you cite...to help supplant multiple definitions of racism with one universalized *new* definition that refers EXCLUSIVELY to the systemic forms of racism.

For the lemmings who dote over Robin DiAngelo and Tim Wise, it unfortunately works -- they eat up Marley's racist poison as though it's ambrosia. They want a "guru" to tell them what to think and how to speak, and she is filling that void. She certainly isn't the ONLY provocateur on Medium with this mindset...but she's just more unapologetic and less tactful than some of her peers.
