if this becomes more common, instead of blaming the unvaccinated, we should ask ourselves "what makes them buy those passes rather than getting vaccinated and get those?".
furthermore, until COVID19, have you ever heard of any vaccines that are widely promoted by people who have no scientific knowledge of those or even mandated by any governments and anything against that vaccine is censored?
all these are just at the figure tips, its not something far away. Like you said, why won't i buy? There is not definite answer to the genuineness of the vaccine. Even people whom you though should have taken are withdrawing. Some Authorities, because the want to lure people to take the vaccine, do a show up on new without any proof that it was actually the vaccine that was given to them.
Why will you ask me to take vaccine and still tell me i am not safe even after taking it? Of course if buying not showing the card is what denies me of thing that should belong to me then i will buy?
If i die then Its my choice
