For myself, I'm not talking about forcing anyone to take it. Just to be clear.
What I am doing is a risk/benefit analysis using the available data. You see the risk to the vaccine is higher than COVID-19, I can find no data to support such a conclusion.
So, lets say you don't get the vaccine, you get COVID-19. You end up with cardiomyopathy. Then what? Both courses of action have risk, one has more than the other. Even your examples of worst case scenarios don't result in the course of action you are choosing being safer. Humans are not rational creatures, you are free to not take it and as much as I don't like the consequences if enough people choose that action, I will protect that freedom (though I will not try to protect anyone from the consequences of using that freedom). If I don't state the facts as they stand I have some culpability in that, so my goal is to be able to say "your blood be on your own head." Some people will disagree with me having any culpability if I remain silent, but I was raised believing that people have an obligation to stand up for what is right and I'm not willing to turn my back on that. That said, I have said about all I can and will probably let everyone else have the floor.
I don't remember you arguing for personal responsibility, so what follows is not directed at you, but those who have.
So, if you don't get the vaccine, and you end up in the hospital, are you going to use insurance to pay for it? Keep in mind insurance is based on pooled risk, so you are increasing risk and demanding that others pay for your action. That does not sound like personal responsibility to me.
