The left has begun "decloaking" their agenda regarding the fake charges of "racism" against patriots.
Whiteness is not being used as a term to describe low levels of melanin in a person's skin. It is now referring to people who are decent, normal, nationals of a particular country. "Whiteness" seems to me to encompass traditional and conservative values, love of country and love of family. The goal of creating a "white versus black" narrative is to marginalize people who usually would be the bedrock of a society. It started, ostensibly, with seemingly genuine calls to address social inequality based on historical disadvantages, but quickly and intentionally morphed into subversion of our history, culture and family based social structure.
It is under this paradigm that you can call Bill Clinton "the first black President", Elizabeth Warren can get a University job as a "woman of color" and racist pedophile Joe Biden can lambaste people of African descent and tell them "you ain't black" when they fail to support him and prefer Donald Trump.
