I get really annoyed with the term politically correct - and the way it is bandied around and used to cover everyone that disagrees with the way some people act.
In another thread I took it that I was being described as pc for saying that I wouldn't like to live in the neighbourhood of someone whose brother sounds like what we call in Scotland a total ned.
If you are having a private conversation and not shouting and yelling in the streets then what you say is private and noone should take offence.
If you are in a crowd of people and shouting racist comments EVEN TO EACH OTHER in a 'banterful' way then you WILL frighten passersby.
Fighting in the street will also alarm innocent people.
Calling people who are offended pc is often just a way to justify bad behaviour.
Political correctness should relate to silly rules devised by people who are scared of offending anyone - and often do not consult the people who are supposed to be offended, e.g. banning Christmas cards, nursery rhymes and Santa Claus.
It is not 'pc' to abhor racism, loutish behaviour and selfishness.
