During high school in the eighties we did work in English or history or both on the reasons behind the diminishing importance of Anzac day and the quite large amount of negativity/hostility towards it by some. A lot of it was due to the fallout from the Vietnam war and fears at the time of a nuclear war meaning the anti war movement was strong
This attitude shifted and Anzac regained its position as a day of genuine reflection but as you say it's now morphed into something else that approaches an ugly time of celebration - I often used to think I'd like to attend a dawn service at Gallipoli thinking it would be quite special but now that seems closer to a rock concert than a solemn remembrance
Yep it's definitely gone that way.
They need to put a limit on the number of visitors for a start. You can't move.
