I love that line at the bottom, Australia is the nicest racist country you will ever see.
Australia and the USA really do share a lot of culture and similarities, but occasionally something comes along that just shows how different we are in our general mindset and outlook, whether it's guns, politics or religion whatever.
This cartoon really shows how crazy the outrage machine is in America, and how the victim culture is growing and shouting louder than everyone else in the room because their feelings got hurt by something and they are incapable of seeing past their own prejudices and preconceptions to listen to the other side of the argument and use logic and rational thinking to come to a conclusion.
There has been some people offended over here, but there has also been a lot of support for the artist, because his intent was clear, to show a champion acting like a baby throwing a tantrum, and thats how most people saw it here.
Although we have a dark bloody history and definitely have racist people, we also are a multicultural society that is pretty successful. We have a sense of self deprecating humour and love taking this piss out of ourselves and our friends, and this is a case where humour has been lost in cultural translation.
Sorry for the tl;dr
