Here's an idea for a next trendy protest: Drunk people against restrictions on driving. Cuz if you're drunk and evil fascist 3rd reich billgates police stops you, then your rights have been violated.
Yet, these antivaxers simply can't accept reality. They are like flat earthers - Earth is round below their feet, but they insist the opposite. Only instead of NASA lying to them, now it's "fascism" (like anyone can give the actual definition of this), the pharma mafia, plandemic. A bunch of delusional morons in agreement with one another doesn't make them right. But for that to be realized, you gotta have a bare minimum of neurons left in the hollow top bone.
Do you see how using such a narrow lens could be unwise? How many boosters are you willing to tolerate to maintain your certificate, 2, 5, 10? How about we make them a monthly requirement, any issues?
The certificate does not stop you catching or spreading covid, but it will make you feel more 'safe' and better about yourself.
It is much harder to take care of yourself when you have less money, also. Typical example from the US is eating cheap, subsidized burgers instead of healthier veggies.
Maybe tackling the stress from the "modern" capitalist lifestyle might help everyone to lead a healthier life. :-)
