Constantly reminded

The media world has, once again, been up in arms about Jeremy Clarkson. Now a BBC disc jockey, playing a record
(a jokey, George Formby type song) by The Ambrose Orchestra in which the lyrics use a word which has been discarded by society.
I use the word society with care of course since there is a whole segment of society who would no longer identify themselves with that PC segment of society, than a supporter of Man U would shout for Chelsea. Over the years there has been pressure applied from the Establishment to protect what are called minority segments in the society from coarse remarks which often had their origin in history or from a time when the law had a different view as to their legality.
You can see the reasoning behind banning certain expressions if the use of the expression is hurtful.   Of course the old rhyme, "sticks and stones will hurt my bones but words will never hurt me" comes to mind and of course like that other expression, when walking down the street and you stumble on a raised paving stone, I would say "I should have watched where I was putting my feet" instead of casting around for someone else to blame.
It seems we are heading, head first into a centrally controlled mind set which if you don't comply you are cast out and castigated. The individual is no longer respected for his/her individuality, conformity is the main issue.
As we unearth words and phrases that could be thought to upset others we also unearth commentary from people who feel marginalised and become another pressure group towards the centre. As a person of the centre I feel obligated to resist this pressure and question whether we are better off to be constantly reminded of the words that used to be used in ignorance and now have the potential of an exocet missile. Is there more harm done to inter-community relations to be always worried about the use of words irrespective of intent. How does a Historian relate to his job, how do we discuss the factors of race, sex, gender difference without our delving into history.
The search for neutrality where the colour, gender, sexual proclivity have been placed off field and make much of our opinion about human experience out of bounds, which not only diminishes our unique singularity but makes us more aware of the potential to upset others and therefore less inclined to join in with the diversity in our society.
