bad mouthing Mel Gibson

I didn't hear what Mel Gibson said but I have heard a lot of bad mouthing of him on account he had said something racist. Why is he not prosecuted under anti-vilification laws if the protesters are so serious in their condemnation? I thought racism was a crime. Why has the State not prosecuted him?
That is the problem. In order to prove you are not a racist or a bigot or child molester or wife basher or any other of these crimes of the heart, you have to be noisy whenever it happens. Which makes it a pity that the noisy people were not around to receive the refugees on the Voyage of the Damned in 1939. How many of these Hollywood types accepted an asylum seeker then? How many did the USA accept then?
As the poet (Keats - Grecian Urn?) said - "Heard words are sweet; those unheard are sweeter." The corollary equally applies - "Heard words are unkind; those unheard are unkinder."
I learnt at school that empty vessels make the most noise. You have to look to the heart and not just to the words because the heart can hide many evil thoughts from other people.
