"Political correctness" was not invented in anglophone world - that's where it got a politically correct name.
It's all about naming things, groups of people, ideas and anything that has a word to describe it, in such a manner that nobody would be offended. That won't do much good to those who were initially offended - because the wrongs done to them still remain unscathed - but it's the thought that counts. When nothing substantial will be done, anyway.
So here's a list of words which were once normal, but have now vanished and were replaced with politically rectified expressions.
As an addendum to this list, here's the list, compiled by Alan Popow, about the PC expressions composed using "challenged".
Not dishonest, but Ethically challenged
Not poor, but Monetarily challenged
Not fat, but Metabolically challenged
Not old, but Chronically challenged
Not ugly, but Aesthetically challenged
Not slime, but Morally challenged
Not a tin ear, but Melodically challenged
Not lazy, but Industrially challenged
Not a klutz, but Dexterially challenged
Not an airhead, but intellectually challenged
Not a slob, but cleanliness challenged
Not a tyrant, but democratically challenged
