Because you're not going to get any answers of substance in this topic. A person died of a possible heart related condition. Why are there so many people asking if he was vaccinated? What does that have to do here? How come no one is asking if he oversalted his food every day? Frankly, vaccination questions in this topic are off-topic.
Well maybe because more and more people have some bad experience with vaccines. Question, that are not comfortable to answer for you, are not necessarily off-topic.
That is your conclusion. I just asked question. Which is, for you, automatically concluded. But you still gave me no answer for that question, which could be really considered as offtopic.
Well... Maybe your conclusion is biased.
"Covid/vaccine related questions should best be left to topics concerning large scale studies, not a single tragic instance."
Why? I prefer individual, non-anonymous source of data. Without conclusions.
