It is not a choice if not getting it threatens your job, your way of life, treating you as a 2nd class citizen, paying extra taxes, being discriminated against. That is no longer in ANY category of being a choice. Which is why we are seeing whats happening.
It's a question of burden.
On the one hand you have people who aren't taking the shot. They spread the delta version when we had effective vaccines that could effectively stop the spread and this small group continues to go to hospitals in overwhelming numbers. They don't want the shot despite the negative consequences to everyone else.
Then you've got people who have gotten vaccinated. And while the new variant is more resiliant in terms of breakthrough/spread there is at least a decent amount of protection. And at the same time they aren't overwhelming healthcare despite being a much larger group.
One of these two groups isn't going to be happy. You may want to fly on a plane or go to a restaurant. It doesn't really bother you if you get others sick or not. Some of these folks aren't even willing to wear masks. However, as a vaccinated person, I don't want you on my plane if you haven't had your shot. I don't want to sit next to you at a restaurant if you haven't had your shots.
One of these two groups has taken steps to protect other people as well as themselves. Moreover, they are helping to stop the hospital surges. And they exist in far greater numbers. I don't see why we should shift the burden to them.
If you don't want to get the shot... cool don't. But that doesn't mean that people want to eat next to you at a restaurant or fly on a plane with you. The burden lies with you. It's a simple shot. Take it if you want to be able to congregate with larger groups. If not, stay at home. Don't try to put this on people who've gone out and taken steps to protect themselves and others.
It's your decision. It IS a choice. And there are consequences that go along with it.
