Yikes! Maybe the people who are asking us to do a welcome to country might know what it looks like!
Honest question, have you ever spoken to an elder about the topic of welcome to country?
If instead we all just went about our business while being silent: checked Facebook, had a piss, replied to an email, then it would cease to be meaningful. And you'd say "oh but what would you know about meaning, the people who know say that you should be silent for a minute!"
I may be totally wrong -- no, I've not spoken to an elder -- but if they think that they're actually getting any respect, or moving forward their cause, by
having companies have someone read the Welcome to Country in broken monotone at the start of a meeting, or
having companies put up banners on websites that you have to click through, or
having the Qantas crew say "laides and gentlemen welcome to Melbourne where the local time is midday and it's eighteen degrees outside and we would like to pay our respects to the people of this land past and present" at the standard cadence of an airline steward,
then I'm going to be politically incorrect and say that they're deluded. And they're worse than deluded: this is at best doing nothing and at worst it is causing harm, because this is causing your regular Aussie to become sick of the whole sorry charade.
Words have a literal meaning, but you don't get the emotional meaning for free. You have to earn that part. I can say "I love you", but I don't love you. This entire country is saying these words but they have lost all meaning in the vast majority of cases.
If you think that's good I don't know what to tell you.
To use your analogy, if everyone took a minute silence but spent it browsing Facebook on their phone, would that be respectful? No, it would be pointless.
Edit: to be very explicit, I think Australia needs to reconcile with its Aboriginal people. I don't know how that looks, I'm not an expert. We should probably ask NZ. But reading a boilerplate statement at the start of a meeting doesn't do that. It makes it look like we're doing something whereas in reality we are doing literally nothing. And it makes good people who might actually want to do something cynical, because they just think "this pointless nonsense again?"
