Using a vaccine card for admission seems rather pointless since vaccinated can still get infected and are as contagious as non-vaccinated. If ensuring everyone is vaccinated helped reduce the risk that everyone in the room was a little safer, I'd be a lot more sympathetic to it.
But the people requiring Vaccine cards are uninformed, not tyrants, so what are you going to do? If it's their facilities, and I want to get in, I'll probably show my card.
When I go to the pharmacy I show my ID, those tyrannical bastards!!!
When I want to use a credit card I show my ID. Those nosey dictators.
If I want to travel by mass transportation, I show my ID. Those despicable brown shirts. They'rrre despicable!!!
I'll continue wearing a mask when I go out, whether places are requiring them or not, because I still believe it blocks at least some particles and therefore may result in a lower inoculum and a less severe disease.
Maybe I'll get me a sheep mask.
I'm a lot more concerned about censorship, fair elections, selective prosecutions, prosecutorial abuse, and dishonesty at the top levels of government including the medical establishment than I am about vaccine cards and masks.
