The time to argue about this was last week and more likely a month ago. Governments both in the UK and US and elsewhere made a decision. Debating it now is the equivalent of arguing about the barn door, once the door was left open. The horse has fled.
It is what it is. We are where we are. Taking adequate precautions, making sensible decisions and listening to government advice at this stage is the only viable solution to minimizing the effect.
You in UK are going to have to face it. The development of the virus is lagging behind Italy, Spain and now France but unless drastic action is taken now it will very soon be out of control.
The "kind" approach is no good, people do not respond.
Last Thursday Président Macron spoke to the nation here, he
asked people to not gather, not frequent public places etc. What happened? fine sunny weekend in Paris and parks cafés were crowded. SO; Yesterday new rules. We are now being
told what to do, and fined if we do not do as told.
Effectively confined to home for the next 15 days; there are exceptions of course, well listed on government sites.
I fear Brits are in for a shock when these measures become essential there.
