The Anti-Defamation League (ADL) is the pre-eminent group in the United States for protecting the rights of Jews and to counter misinformation such as the denial of the Holocaust.
Yet the ADL works within the free-speech laws of the US. It does not have a campaign to change or repeal the First Amendment of the US Constitution. It knows that free speech is vital for the protection of minority groups such as Jews.
The ADL is well resourced and highly influential. It works through education and persuasion. It fights anti-Semitism effectively through a range of methods, while respecting the free-speech of its critics (after all, there are more Holocaust-denial websites in the US than in Australia).
That is the model Michael Danby should be advocating in Australia, not using the racial-vilification laws to silence Holocaust-deniers.
