So your issue is with our anti-vilification laws. I make no apologies for arguing that we should protect all groups vulnerable to vilification. Currently we do not because our anti-vilification law only protects people based on race and religion.
On the point that you don’t think there should be any limits at all on free speech, I disagree - publicly calling for minorities to be murdered is a clear red line. Defend that if you want but I certainly never will, because I understand that few human rights are absolute (the right against torture is an example of one that is). Most human rights need to be balanced against others and there is a substantial body of literature by human rights lawyers, advocates and organizations detailing how best to do so.
