I think this is missing the point slightly. The vaccine/viral infection -> exercise -> myocarditis link is a well known (to the medical community) link in other vaccines/viruses, including flu. Therefore the "burden of proof" should not be to show that there is a link here too, but to show that there isn't despite it being a common thing in so many other viruses. Therefore, the fact that people are not given advice not to exercise heavily following vaccination, especially in professions where daily heavy exercise is the norm like in the military, is causing unnecessary morbidity. To come and say "yeah but it's still small" is not "putting things in perspective", since this is morbidity that is likely entirely preventable and unnecessary.
