The "political correctness" you and those like you disdain so much was and is all about treating others - ALL others - with a degree of respect and dignity.  It was neither liberal or conservative in its use.  and certainly was in part intended to get "White America" to change its racist and xenophobic language.  It went hand-in-hand with ridding ourselves of racist and discriminatory laws and practices, of advancing society in the best of our core values be it from law or faith, and in making racism, white superiority, and discrimination against other citizens of this nation to be unfashionable.  And you object to this, huh?  You never, it seems, could see beyond the cultural racist and self-serving attitudes of the old social condition.  That is regrettable, even if you remain blind to it.  You have missed out on so, so much.
