Political Correctness is a deflective mask to shield lazy, un-compassionate people from actually wanting to know what the other thinks and feels. Once they can go tsk tsk, they feel satisfied that they have done their bit for humanity and justice and all the racial problems of the world. Feeling satisfied and self righteous the politically correct police no longer have to actually delve into inequality of wages, and status in not being promoted or obtaining the better jobs, or being shown in museums, being made CEO, or the feelings of the other, you know the real stuff of the world.
Once you can tell your neighbour who actually cares about injustice and is irate, that they have said the wrong phrase or made the wrong gesture or painted their face inappropriately these self-righteous morons can sleep easy without lifting a finger or spending a penny in actually helping people to lift themselves up or chastising their bosses for real human rights abuses.
Political correctness needs to be stamped out to make room for authenticity of speech, and relationships. For the realization that we are in fact all human beings in all the same ways that matter, that we are all deserving of fair and just treatment!
