It's building a national cast system based on loyalty to the government and eagerness to accept their propaganda

Western society has become an antisocial one.

💯 correct

Here in the Netherlands a bill is moving that will legalize private corporations collaborating with the state in order to mass spy on and stalk citizens.
I recommend checking if something similar is happening in your country.

Don't just protest against the passport itself, to do that is to play only defense. We need an offense... protest against the people who inflict this passport on society, attack them as being immoral, impugn their motives, ridicule their behavior, typify them as brownshirts, goosesteppers, prison camp guards, dirty vaccinated spike-shedders. In other words, create a message that gets through to them personally, because otherwise they will just ignore your blather about an inanimate passport and what it's doing to you. Make the issue about them, not you, and always attack, never defend.

Always remember THIS!

My vaccine passport ist still ... ehm ... from the previous regime. It's red with a hammer and a circle on it (not kidding).

Showing my vaccine passport will be so much fun!
