You are engaging in a red herring argument. In the vast majority of cases myocarditis “is brief, self limited, and of mild symptoms”. The baseline number of cardiac events in soccer players is not statistically significantly greater after the introduction of vaccinations.
Additionally, it is not unreasonable to understand that athletes have a high incidence of cardiac issues related to connective tissue disorders. But, this would require an actual understanding of pathology rather than a cutting and pasting of an article that is unrelated.
The behavior of the medical community, media, and world governments has required us amateurs in the field of medicine to delve into it. These entities have clearly demonstrated that they cannot be trusted.
Maybe us rubes don’t always get it right, but we’ll eventually figure it out.
I suspect that’s what everyone’s afraid of.
