and material that is produced specifically to cause harm (such as material published to incite violence, hatred, oppression, etc).
Aah, and in that you've hit the nail on the head.
Censorship happens because its feared that its absence will cause that most terrible of acts - 'offence'.
OFFENCE? Do you know that it is now a CRIME to cause offence by means of sexual, racial or religious discrimination?
But why is it that I could call an obese person 'fatty' without any repercussions at all? It's discriminatory, and would probably cause an awful lot of offence to that individual.
Ageism is something a lot of people feel passionately about but the government takes no real action at all. In fact people are often sacked because they are 'too old', even though there is no apparent evidence that the standard of their work has declined.
Or what about the average, white, heterosexual male - a group of society alienated by almost all attempts to stop other groups of society feeling alienated. They are demonised by the press as racist, uncouth and yobbish - which we all know isn't true.
Okay, a little off of the point, but censorship is a means to an end. And what is wrong with people being offended once in a while? It might stir up opinions they never knew they had.
