I don't think most people who choose to not wear a mask or choose to not get "vaccinated" to be boneheads.
This bubble chart is a visualization of "Grandma Alice's" social connections for the week. Many of the connections are so fleeting as to not count. Each week looks much like the last. Very few new people rotate into her life.
Grandma Alice refuses to wear a face diaper or get the vaccinations. I don't consider Grandma a bonehead.
This bubble chart is a visualization of Amanda Grogbottom's weekly interactions. Amanda is a social, college-age girl who likes to go to parties. Amanda does not wear a face diaper and has no intention of getting the shot. One notable difference between Grandma Alice and Amanda is that there is very little overlap between the people Amanda meets from week-to-week.
Depending on the nature of the parties, Amanda might be a bonehead. If the parties involve sweaty slam-dancing, passing a doobie around, multipartner sex, people puking all over the floor and then dancing in it, and fisticuffs, then Amanda IS a bonehead (especially because she didn't tell ME about the party). If the parties are outside and involve sledding down hills or playing disc golf...probably not.
I don't know if this post clarified anything but I met Mr B and don't think he is a bonehead.
