It is a quirk of the Hate Speech laws that, as I understand the law, saying that to noone in particular is not an offence, since it is not directly an incitement to violence. In NSW, this is the wording of the offence:
93Z Offence of publicly threatening or inciting violence on grounds of race, religion, sexual orientation, gender identity or intersex or HIV/AIDS status

Of course, my opinion is that the current worldwide increase in overt racism is the product of what we are told is the World's greatest democracy, and you know which one I mean.
