I believe I get the gist of what you are saying. I guess if you focus on the extremes of the left or the right you will come up with conflict and intolerance to opposing views. The point I would like to make is that these extremists are are very small minority and not representative of the general population in Australia.
Australia is one of the most tolerant laid back countries in the world built on the back of immigrants from a broad range of ethnic backgrounds. In the main people here live peacefully and cherish their freedom and secular democratic way of life. In fact to Australians that freedom and democratic way of life is the thing that they have fought to keep and protect. Australia is indeed the lucky country and we need to keep it that way.
