Yesterday we looked at the basic argument behind the prohibition on racial vilification in section 18C of the federal Racial Discrimination Act (RDA). That prohibition is followed by section 18D, which provides for exemptions to 18C. Defenders of the RDA insist the exemptions are so broad that only the most egregious cases end up being prosecuted. That may be true, but misses the point that no exemption can make the restriction on free speech in 18C legitimate if it isn't already so.
The exemptions in 18D are important for another reason. They exempt "anything said or done reasonably and in good faith" in the course of artistic, academic, scientific, or journalistic work (both reporting and commentary, if it's the expression of a "genuine belief"). There's also a catch-all "any other genuine purpose in the public interest" exemption.
