The "Racial Discrimination Act " is a bit lopsided and really only works one way and for specific races.
I have never heard of a white successfully prosecuting anyone for being called a white "so-and-so", yet it happens daily, doesnt it? People still get called dings or wogs, Serbs no doubt have endearing names for Croats & vice versa. If any of the above ran to a cop and said "Arrest that guy, he called me a.....", what do you think would happen? "Nothing" is the correct answer.
