Well the particular person I am thinking of I knew quite some time ago. She is my ex-sister-in-law. My brother divorced her years ago which bankrupted him, and left him only with the satisfaction that he was free of her. They had two now adult children a son and a daughter.
The son was a PO in the US Navy and did several tours in the Persian Gulf including a stint as a Marine Corps Sergeant. His navy rank was equal to Sergeant and he was a qualified medic so the wet navy loaned him to the grunts.
The daughter just had a son of her own so my brother is now a grandfather.
So now on to my ex-s-i-l the anti-vaxxer. She was and is more than a little strange. She is not stupid as she has a University Degree in English and worked for years as a technical manual writer. But she has an amazing ability to not think. If she hears an opinion from someone on something she files it away in her head as another thing she does not have to ever think about.
When she was young she heard someone her dad knew say that Volvos were good cars. Back then they were reliable, tough, and solid safe cars. I think they invented seat belts. Well after that she would refuse to own any other car brand. When my brother wanted a sporty car he got a Toyota, but she refused to ride in it. He was sick of Volvos.
When the young couple were going to build their dream home she found a contractor that someone said was really good. She gave him a big deposit on the work and he disappeared with the money. She refused to believe that it happened, and he would get back and start the job real soon. Never did.
When her mother had a fight with her older sister she would have nothing to do with her for the rest of her life. She objected to her coming to her wedding as she was an enemy. I met her there, and she was very nice, pretty, and did not ride a broom to the event as I was told she would.
My brother went to visit his new descendant and his daughter made sure he was fully vaccinated for all the current nasties in the world. He was so prepared. He lives in Australia where they take health care seriously you know. He was told that his ex was not permitted to visit as she refused to get any vaccines. The new mom inherited some of her mom's stubbornness, but in a good way. No shots no visits.
Good for her. Protect your baby with your life from stupid people.
Volvo girl has even bought into the Bill Gates microchip nonsense. I mean she used to work with engineers and she thinks Moderna is shooting GPS receivers into your blood. Physically impossible nano-bullshit.
So in exchange for being a stubborn misguided person she shall never meet her only grandchild. Sort of basic justice there. I am sure she will never admit her error. I can see her forging vaccination certificates. Maybe even kidnapping. She is that far gone.
Were it not for vaccines there would be a lot fewer live people in the world and many would be crippled. When we were young even kids knew the risks of not getting vaccinations. Now all it takes is a former Porn Actress to blame her child's problem on an imagined vaccine issue rather than her own drug use. Add the social media algorithms that bring bad ideas together with stupidity and here we are.
Volvo girl is not alone. My wife's oldest and dearest friend is a degreed Nurse. She worked in an emergency room, was a small community health administrator, and has all the outward appearance of a smart qualified professional. And she told my wife don't get those vaccines! She read on Brietbart that it was all a global conspiracy blah, blah, blah. This person should know better. But she is easy to persuade to do the wrong things. I could go on to list her ex-boyfriends and a husband as perfect wrong choices.
Some people hear some idea that they like and that is it. Rigid thinking unable to fit in new or better information. Why they pick this or that is a mystery, but once set it is in stone. Stone headed thinking.
This is a symptom of our age. Our age is sick.
