The murderous attack on the office of French magazine Charlie Hebdo has renewed the debate in Australia about Section 18C of the federal Racial Discrimination Act 1975. Free market think-tank, the Institute of Public Affairs, has called on the Abbott Government to repeal Section 18C. The Australian Christian Lobby (ACL) has also backed calls for the Government to revisit the debate about freedom of speech. ACL Managing Director Lyle Shelton said all public debate should be conducted respectfully but it should not be against the law to ‘insult’ or ‘offend’. ‘Inciting hatred or violence would still be an offence, but not ‘insulting’ or ‘offending’,’ Mr Shelton said.
