Do you feel you're being completely fair and rational, or maybe just a tad silly because someone has a different opinion than you, (and possibly due to a completely different set of circumstances and variables than you)?
Everyone that hasn't been vaccinated, isn't holding out due to fear of the potential dangers. Some have VERY good reasons for holding out, and some have a MUCH better understanding of their personal risks compared to others where ignorance is pure bliss.
There are millions out there who even think the new vaccines are exactly like traditional vaccines, simply because they've been duped by the deceptive propaganda, or because the name is the same, (and those folks are really wondering what all the hubbub is about, and can't for the life of them, understand why anyone would have reservations). These are the types that are most likely to call others cowards or attack or pressure them, without stopping to think and grasping the totality of the situation.
