I just got back from France 2 weeks ago. They're taking practical measures to save themselves from a deadly disease.
They have their vocal, trash burning, antivax nutters but in my travels they're all on board with the Pass Sanitaire where you show the qr code from medical services either on your phone or a printout to go in stores, bars, nightclubs.
In Tours they were unfailingly polite but firm about it.
I didn't see any people going nuts. Masks are required on public transport.
