Are you asking if there is a place for political correctness?
If you are, then I think there most certainly is a place for language (and behaviour?) which doesn't demean or belittle or offend. Although some people might think that this is taken to extremes I have often thought that an extreme view or behaviour is often helpful in producing a moderate change in views and behaviour.
Of course change is resisted but, if you think back to, say, the 1970s I'm sure you could find a fair few examples of language or attitudes which were commonplace then but would now produce acute embarrassment or disgust in an onlooker. And the reasonableness of the motive for not doing them is understood, without any resentment, by most people. Would we really find Alf Garnett funny these days? Or be amused by depictions of women as incompetent half wits? Or would we approve of calling a disabled person a spastic?
I really dislike the term 'politically correct' because it was coined as a pejorative description and has never stopped being perjorative. Yet the motives behind the attempts to change attitudes and language have been mostly really good; to attempt to make all members of society feel valued and to recognise that they must not be stereotyped and held back by that stereotype.
