No one is trying to rewrite history we acknowledge that what happened in the past was unfathomable and abhorrent. But current day Australians bare no responsibility to past happenings.Actually what he's upset about is people wanting to rewrite history and think the past is irrelevant, you can do both if you decide that both views are equally as important but many choose to dismiss the concerns and grievances of the indigenous community because they don't want to understand it. You seem like that sort judging by your views. There not against having a national day which seems to be getting lost in this debate, there against the specific date.
Most including me are sympathetic to the past but also proud of the country we are. the left won’t allow you to feel proud to be Australian automatically labelling you a racist.
Whatever your mindset is tomorrow I hope everyone finds their inner peace.
