They don't really get it.
They also don't get that anything they feel adressed for, or consequences that they have in life for not taking their vaccine is a consequence of them not wanting to take a vaccine. It's a choice. Jewish people in NAZI occupied territories and Germany had no choice. According to NAZI ideology, they were born as Jews, it's part of the blood. You can't get rid of the label, it's just who you are no matter the choices you make.
But most of these people want to have their cake and eat it too. Make descisions have no negative consequence, because they believe that hey are the good guys. Instead of self criticism and trying to figure things out, it's way easier to play the victim and pretend that you are being persecuted by a bunch of bullies. Self reflection is for other people when you convinced yourself that you are unable to be wrong.
