Bill, himself, continues to marginalize.
Bill’s “get over it stances” are usually off base. He’s more and more a Centrist or Blue Dog Democrat. I too have followed him for a while. People concerned about life issues are turning more and more into whining people to him. Furthermore, political correctness does not appear to be a term that most movements even embrace. Anti-police brutality, the prison pipeline, wars, income inequality, gender rights, human rights, poverty, poisoned water, #DAPL, campus protests of offensive comediennes, etc., all have nothing to do with political correctness when the offense is opposed because it stirs up even more harm and death.
Like whiny people, political correctness is also a misused and overused term. That, and Bill was at a total loss about how to defend the marginalized against his rant filled guest, a guest whom Bill bent over backwards to try and find common ground with; a move he makes, presumably, for continued alt-right access.
I’m ranting now, read the article by Ms. Ukoha and here; they’re more focused.
