The ugly face of Australia Day on the NSW North Coast

While elsewhere on the NSW North Coast backyard barbecues were fired up, small street parties got underway and people travelled to see their local heroes honoured; young hooligans in the Coffs Harbour area drank too much and got into drunken fights for all the world to see on the teev nightly news.
Yelling insults and wildly swinging their fists while draped in the Australian flag - acting like prize nongs that their grandmas would disown if they could've seen them.
When did our so-called national day take on such an ugly face across the land?
Why do our youth appear to equate patriotism with violence or racism?
Do the young feel free to act like this because they grew up in the Howard years or is it something even darker?
