Growing up in the 1970's, i remember the jokes comedians made about black men, the Irish, the disabled, Jews, homosexuals, women and any other group that wasn't British white male.
Fast forward 30 years and we have shows like Little Britain and Borat which are applauded for not being politically correct but are exactly the sort of shows that wouldn't have been funny 30 years ago because the sort of thing's they say and do were then the norm.
As if undermining the people applauding him, Borat writer, Peter Baynham, explained that: 'When Borat says controversial and 'un-PC' things, it is obvious it is because he is clearly an idiot, a little reminder, of why we don't say those things, and it's weird when you read people saying it was deliberately offensive. The laugh is a laugh of 'Oh my God, you can't say that!' People are laughing with shock, because we've reminded them of why it's wrong to say things like black people have chocolate faces'.
Far from being a mockery of political correctness, Borat shows a time before political correctness made things better and that is where the humour lies, laughing at the very sort of 70's racism and sexism that was so prevalent and ushered in the dire need for cultural and social advances.
A peaceful society is built upon respect and tolerance for all of it's members and since the days when Bernard Manning's jokes about Paki's was the height of comedy, Britain has become a more tolerant, fairer and more culturally aware society and the introduction of political correctness has helped promote that.
Political correctness reflects the kind of society most of us want to live in where offending people is frowned upon and it is only those who set out to deliberately be offensive who complain about the restriction of their freedoms to insult anyone they want at will.
The phrase 'political correctness gone mad' can be heard being uttered by aggrieved people who remember the days when they could speak without fear of being accused of upsetting one minority in society or another.
Political Correctness has ushered in a time of respect and civility for all, where unnecessary offence is avoided and everyone in society has the same opportunities regardless of the colour of your skin, if you are in a wheelchair, if you are Jewish or if you have a vagina and how can anybody seriously say that is a bad thing?
The only freedom the anti-PC brigade has lost is the freedom to cause offence to another person and thankfully we have moved so far from the bad old days that no amount of whinging about political correctness will undo the immense good that it has done.
