A poor argument. I'm unvaccinated because I am unconvinced that it is in my or society's beat intereat for me to do so. The avoidance of shaming those who are not vaccinated should be:

1) Because telling someone they're stupid almost never works when they have a community of people who agree with them.

2) Because it activates moral faculties that keep the shamers from contemplating if they might be mistaken.

3) Because bodily autonomy is an important enough issue for a principled stance to be taken against even effective and safe treatments.

I think shaming the unvaccinated is foolish, but playing to people's empathy to prevent it? That's the thing about "othering" a group: empathy no longer exists there. A poorly constructed emotional argument, but perhaps the only kind allowed here, as evidence based discussion of why one might not want to get the shot is an instant ban hammer.
