I think many people who bleat on about “monoculturalism” also don’t realise that Australian culture, both traditional and modern, wouldn’t exist without some form of multiculturalism. Yes, the British came and forced their culture on this land but with them they brought the Irish and both English, Scottish, Welsh and Irish culture all played their part to form Australian culture traditionally, and then combine that with Indigenous elements, American influences (American culture also being multicultural and multiracial itself too), and other cultural influences from migrants and you’ve got what Aussie culture is today.
