Its a changing world Bob. What we see all too often is a minority group lobby for change as it affects them, neglecting the majority who are content and are not motivated to either change or challenge the status quo, then the changes affecting the few are pushed onto the many. For me, I am not fussed if they change the date or not. I don't really have a reason to object and can understand the objections by the indigenous community or at least the 'activists'. What would be interesting is to see what other countries do regards this same issue or if they have a single day of celebration for establishment of a new colony. I am equally happy to leave the day/date/name as it stands, but can see if the Aust Govt eventually moves towards a formal acknowledgement of the 'nations first people' then this may well be a more compelling driver to change the date or change the actual name of it. There are a number of different 'causes' coming to a head that have been accepted by the many as normal, but despised by the few who take objection to them or believe they are adversely served by them. Unless you go to the expense of the Same Sex Marriage survey, you will always get an outcome that depends entirely on the vigour of the affected few, and how vocal they are, regardless of the merit in the bigger picture. The Greens are notorious for their championing of the 'under-dog' or minority, and the move has already started by stealth I believe to change this date - ie simple 3RRR moving of their long standing best songs of the year away from the day - its a small change, but its the start of a larger crack forming. Apologies for the long winded response but it isn't a simple issue, or at least from where I stand.
So I guess the message is, fight the bastards at their own game - get organised and vocal and get your point of view out there, front and centre.
