As the saying goes, you can't please everyone, but you can tick everyone off.
In the 90's, there was a point where someone proved the former by demonstrating the latter. I speak of the disparagement of Political Correctness. It is a favorite punching bag of the American Right Wing, who see it as some sort Orwellian new-speak meant to undermine the English language and somehow, by extension, the ability of people to speak their minds. As the Right has very often shown itself to be the party of going with your gut, couching language in circumspect terms is a small act of surrender.
And yet, I think there's a very good reason that political correctness exists and should be used by our politicians, news media and other speakers operating in a public forum but not in the realm of fiction (yes, I'm still including politicians and reporters in that). The essence of political correctness is attempting to say things in as non-confrontational and inoffensive way as possible while still being accurate. Given that the people I mention make their living, primarily by talking, it seems somewhat strange that we would not expect them to do it without upsetting a large number of people.
The fact we don't demand such a thing seems strange to me.
Now, political correctness can be take too far, much like many other good ideas. If it hinders our ability to speak to the point we can barely talk about potentially sensitive subjects at all, then it fails to serve its purpose. And it has been taken to some very silly levels in the past.
But that said, I think it is better that it is a part of our public discourse than not. After all, if you don't watch what you say, you end up having to apologize for gaffes like implying Republicans are would-be slave masters or come within a hair's breadth of refering to the President of the United States by a racial slur.
