"Not taking Biden seriously" has very different consequences in civilian life versus in the military. The military doesn't ask new soldiers if they will take vaccinations. They tell them to stand in that goddam line, you maggots. "Opting out" gets you the stockade. And they get a whole lot of vaccinations that are far worse than Covid vaccinations.

What happens when Covid vaccinations get added to the list of mandatory vaccines to attend public school? Every public school district already has such a list. Why should the Covid vaccine be treated differently? I bet a lot of the anti-vaxxers will discover they can't afford private schools (who may have their own vaccination list) and opt for home school. And then get arrested for failing to home school in a legal manner.
