I know 3 from my teenage years, one of them a stroke, something you claim doesn't happen to young people. Stroke actually isn't that unheard of in young people, just not exactly common. I don't know if it's spiked the past 2 years, some of that data isn't even available in Australia yet as all cause morbidity data only goes up to 2020 atm. Yeah, the insurance company stuff is interesting, but still, need more information to tie it directly to the vaccine imo, worth exploring further but likely won't happen.
The laughing part I refer to is the vaxxed laughing at some of the unvaxxed who died, but then later die themselves despite being vaxxed. Like the aussie food review guy a few posts above. I've seen people laugh back, but I see it as God sending a clear message not to poke fun at someone elses misfortune or you just might be made an example of.
I hear lots of anecdotes about vaxxed getting covid many times, unvaxxed never etc etc but I don't see any rhyme or reason to it, some of it just might be pure luck. I'm not advocating for the vaccine anyway as I'm not vaccinated, and have not had covid despite almost everyone I know who is vaxxed has had it (most people are vaxxed in Australia though).
