In my experience the Irish-Argentine community are quite aware and reverential of Irish culture. Irish-American culture is another animal, it's more the fusion of American and Irish values. Not saying that's bad.
This Scottish day business however should involve more mid to late 90s Scottish indie bands,re-enactments of the archie gemmill "moment", less bagpipes, more whiskey and as many spurious references to irvine welsh characters as possible.
