I know how you feel about the people not staying on track during covid.
My wife's family has always been one of those "let's get together for every holiday and birthday and if no event is on the calender get together anyway for the heck of it since it's been three weeks" whew!
Although my wife's side of the family (her sister and brother and their spouses) were not covid deniers, all during the last half of 2020 they kept having family gatherings. I refused to go and complained to my wife about her going. They just didn't get it that each of them had a circle of contacts and that by mixing all five of them (and their kids) they were simply creating a ven diagram of intersecting possible covid contacts!
Finally, in December 2020 I pushed back on her again because her sister wanted to celebrate several birthdays on one day with a gathering of 10-12 family members. I convinced my wife to tell her sister she would not go.
My wife and I avoided covid until after at least one booster when we got a mild case in August 2022.
I do know of someone, a former coworker from the years 2004-2014. He was an uber-libertarian, government hating, can't tell me what to do, conservative Opus Dei type catholic. I saw a post on LinkedIn from our alumni group of that company stating he had passed away. I checked his obituary and it did not indicate the cause of death. So I asked in the LinkedIn thread and was told covid. This did not surprise me- no government was going to take his freedom away by mandating masks and social distancing and gathering in groups. So he died about the age of 50.
