I agree with what you're saying. It's very important to send positive messages: we'll get through this, we'll soon have enough medical capacity to treat everyone who falls sick, we've weathered worse crises in the past and this one won't be the one that beats us. I try to do that and encourage other people to do it.
But it also needs to be made clear to people who propose to build a dystopian society that this is not okay. No amount of fear makes it justifiable or understandable to propose that your fellow citizens should be rounded up at gunpoint.
First part is good. Second part of "needs to be made clear" is where you will run into issues.
We have this need to get everyone to agree with our views. But firstly it's not important to get things done and secondly it's not possible because of the variety of different needs and personality traits in the population.
It's a possible approach only on Putin or Xi planet . But it breaksdown in democracies (esp given the propaganda these days) people just harden their positions(they hear your view as an ultimatum or a demand), get defensive, react, attack etc. Trust breaksdown and then there is no hope for anything nuanced.
Better option is to give people something else to focus on, something to do etc while doing everything you doing well in your first para.
It's intended as an ultimatum and a demand. At some point we have to shift from calming people to fighting back; we can't wait until soldiers are in the streets to say that months of martial law is unacceptable.
Protecting your interests (economic, freedom or whatever else) sounds like your goal. Ultimatums are the route you are choosing to get there.
And the point to remember is ultimatums work when you have established authority and power over everyone else ala Xi, Putin etc.
In democracies it doesn't work because power is distributed. To force the political/judicial/business/military/intelligence/religious/social/media circles in all parts of the country to all bend over is probably the most complicated route to choose to get to your goal.
But it also needs to be made clear to people who propose to build a dystopian society that this is not okay. No amount of fear makes it justifiable or understandable to propose that your fellow citizens should be rounded up at gunpoint.
