It is extremely important that you keep your opinions on these matters to yourselves, lest you be hauled in by ASIO or something down the line for even refusing to agree with a co-worker about the lockdowns. The stakes have never been higher.
Sorry, but I think that is absolutely the opposite of the right thing to to do. That mentality is how totalitarian dictators get their way; by keeping people in fear of speaking up.
Granted, I don't know how bad things are in Australia. But I make sure to never, ever, agree with anything people say supporting the covid hysteria. I don't get in anyones face or try to start a debate, but I will never agree or even say "mm-hmm" when anyone says anything at all that goes in favour of the covidian beliefs. My experience is that people often pretend to support the madness precisely because of the mentality you seem to advocate. When they sense that they don't have to play the charade with me, they will often subtly question the whole thing.
And I always make sure to agree when people question and criticize the covid insanity. Not in an extreme manner, by going full Alex Jones, but just by nodding and agreeing. And also making sure to drop some simple facts that they can use in further discussions. For example that Sweden didn't have a single lockdown, and have had no more excess deaths than any other european country. And that the survival rate for "covid" is just the same as for the flu (that is because it
is a flu variant, of course, but that is taking it way to far for most people to go along with). Just giving them some basic facts that can be easily verified even by a normie.
I can recommend you read "They Thought They Were Free", about the rise of Nazism in Germany in the 30s. People not speaking up is precisely why the nazis gained ultimate power in the first place. And the more people go along and don't protest now, the harder it will be to protest in the future.
I think you display a very defeatist and counter-productive mentality in your post. Maybe I misunderstand you, in that case I am very sorry. At least you made me finally register an account after many years of just reading posts, so good on you for that.
