"Get the vaccine or you can't participate in society"

I got no answer from these fanatics on Reddit when I asked why anyone would want to be a part of a society that just throws you away the second you don't fold and relinquish your bodily autonomy?

If it comes down to that I think there's going to be people that would rather just live on the outskirts and survive like highwaymen since they no longer have to follow the rules of a society that made them pariahs.
