There is no safe solution, it's a decision between protecting the 0.5% old, obese, and sick or the 99.5%
How to avoid it is the real discussion.
I could avoid it easily until now because everybody wears a mask here.
In some cases or in some countries, this is not possible, or too much people are infected already, and lockdown becomes the best solution.
Nobody is saying that lockdown is the only solution in every case, and absolutely nobody is even thinking that lockdown is making people happy.
Correlation versus causation.
We're in the middle of a major health emergency. Why are you attributing those to the effects of lockdowns, rather than the effects of the pandemic? You don't think that the risk to personal health of a potentially lethal virus, seeing older friends and relatives dying, and worrying about the risk of health systems collapsing are causing any of the above?
In March, someone I know in Italy passed on the virus to his grandfather, who died at home. All the ambulances in the area were tied up for hours. You can imagine the effect on his mental health. I doubt the impact was comparable to the effects of intermittent lockdowns.
(To avoid misunderstandings, evidence does not mean your unverified opinions).
I'm particularly interested in your methodology for arriving at 0.5%, so a detailed data dump on that from you would be very useful.
