Political Correctness originally referred to going too far in one direction.
Going too far back in the other direction is hardly the answer.
It's exactly the answer. Political correctness is a rejection of common sense pragmatism the vast majority of the time. It prevents a dialogue on the actual issues in favor of a standardized "acceptable" viewpoint, like something out of Orwell's 1984.
Case in point, this whole "Black Lives Matter" nonsense. We cannot have an honest dialogue on the actual ISSUE of culture, which is the root of the whole problem, because people are uncomfortable challenging other cultures. We can't discuss the 75% illegitimacy rate among the black community. We can't talk about children with no father figure and no parental guidance being raised in a culture of violence and gang activity. We can't mention how these kids are suffering from sub-standard education and teachers who are sorry and pathetic. We can't bring up the peer pressure faced by inner-city minority youth to become involved in criminal activity at an early age. All of these things fall under "Culture" and it's "politically incorrect" for us to challenge someone else's culture.
It leads us to these silly arcane notions that we can solve the problem by implementing another social program, throwing some more money out there to be squandered and wasted by bureaucrats and opportunists. It causes us to find other scapegoats to blame... like racist cops... or racist Republicans... greedy rich white privilege... etc. The Problem is The Culture.... and until we address that problem, we will never find solutions.
