My theory is that the group of those unvaxxed that don't need the vax are so small that any rebellion effort would be squashed immediately. And really, the only place where you actually "fight back" are in democratic societies through legislative efforts. I'm only suggesting that the ones that are crazy enough to get violent in their efforts are those that are in such poor health, a flight of stairs would result in cardiac arrest. So we don't need to worry about those folks.

Now, if the common sensed vaxxed population who believes in personal choice and freedoms come together with the unvaxxed crowd, you have a decent chance at defeating mandates. But given how polarizing this is, hardly any of those people left.
