The 'P' word v. the 'F' word

I'm interested that there is so much attention paid to whether or not Andrew Mitchell used the word 'pleb', and not to his adverbial use - as he admitted himself - of the 'f***' word: "Aren't you supposed to f***ing help us?" The word 'plebeian', as anyone with a classical Latin background (patrician perhaps) will know, means common, vulgar, boorish, undistinguished and unrefined. To use it is to demote someone to a lower class - and the British are still obsessed by class. I find the 'f***' word much more offensive, and ironically it is often a sign of a limited vocabulary. Perhaps Mr Mitchell is not the well-educated patrician he would like to be.
