Whats happening to the "Greater British" cultural identity?

Unfortunately the left wing politicians changed the Australian political landscape to the worst. It is not fashionable to be British, it is fashionable to be multi cultural. It is not fashionable to talk about the lawful regime of Ian Smith in Rhodesia, it is fashionable to talk about Mugabe's Zimbabwe. And the list can go on. We should bring back the good old times what we enjoyed in Great Britain and in the Commonwealth during Sir Winston Churchill's time.
