Have you been living under a rock? Half of Australian english is based on "Americanism" as you call it nowadays. Who are you to say they refer to their nationality as their ethnicity? You don't know this. If you have a problem with all the articles with hyphenated ethnic names, then take it up with wikipedia and make a complaint and state your reasons. They will listen to you and if they feel that it is also bullshit, although I doubt this as there are a whole heap of these articles, they will delete them. No one would call themselves Anglo-Celtic Australian either, so what's your point? 

Why are you trying to debate culture now as a reason for your opposition against this article? 

Again your opinion and I am not sure what relevance this has.

Did you even read my reply to you? "Yes, I am aware that there is no reference in the Australian Census about Latinos but this is trivial, there does not need to be any reference. You seemed to be confused on who actually is Latino and this seems to be your main point of debate. Going by your logic the pages Anglo-Celtic Australian and Black Australian should be drawn into question as they are also not referenced in the Australian Census.". I am reverting your edit, and if your truly feel additional citations are needed and choose to revert my revert, then you can be the asshole who sticks this same template on those two pages as I am not going to. And you need to be fair.
