I'm with
@catalog on this one. When you look at the ways in which this government is becoming increasingly authoritarian, they're mostly to do with suppressing dissent and reinforcing the security of the state. So now it's essentially illegal to hold a protest that someone could conceivably find "annoying", which makes you wonder what the point of a non-annoying protest is - but most people have never protested against anything and have no desire to, anyway. Now if you consider movements like BLM or XR, many people obviously don't give a toss about them, and some people are actively antagonistic to their aims, but even a lot of people who think racial justice and fighting climate change are important and worthy causes in the abstract nonetheless don't agree that shutting down airports or motorways is a good way to go about it, and are more likely to write to their MP or sign a petition on Avaaz.
On the other hand, many people who are broadly apolitical, and even reactionaries who think Priti Patel has the right idea about letting asylum seekers drown in the Channel, are going to baulk at the kind of "VHERE ARE YOUR PAPERSS!!!" authoritarianism represented by mandatory vaccine passports.
To put it another way, I think the future of authoritarianism in this country is closer to what the Republican party is doing - ever-stronger anti-immigrant rhetoric, voter suppression via mandatory photo ID, a continually escalating "war on woke" - than social credit or vaccine passports in the Chinese/French mode.
