You can get sick with the vaccine and it is possible to not catch it while not vaccinated. My dad just got over COVID and had been vaccinated and boosted. It isn't going to stop anything, either way. If it works and you have it you have nothing to fear from me without it. If it doesn't work it doesn't matter if I have it or not. Either way it doesn't matter if people don't have it. What does matter is people forcing other people to get it. None of their damn business because logically it cannot affect them whether one does or does not have the vaccine. It's a personal choice.
The vaccines that were mandated on school children were done so because the diseases 1) could be eradicated by proper vaccination and 2) the diseases had secondary effects that were fatal or debilitating. COVID does not affect school children adversely. They will not become sterile or unable to walk if they contract COVID. They will not die if they contract COVID. And COVID will not be eradicated if people get the vaccine. And those mandates occurred before they realized that it was the giving of aspirin for fever that caused the deaths of most of the children affected by many of those affected diseases.
For those that strongly are against mandates, despite what Bison thinks, personal sacrifice (fun) is at the heart of the boycott process. It is not silly to give up your own measure of fun to support what you believe. If everyone believed that mandates were a loss of freedom, which they are by definition, and boycotted any business that supported the mandates, those businesses would be run out of the market or be forced to relax their position. That is the crux of the process and how change happens in America.
The vaccines may not matter to some folks. But if the government is allowed to mandate these vaccines and no one stands up against it, then the next mandate will be much easier for them, with precedent, and the next mandate may be something you do care about. Reap what you sow.
