Never said that there's not some casual causation occurring but the point is more that the article is alluding that it's more than casual and is widespread and that pilots should be grounded. Which there is absolutely no evidence worldwide of pilots becoming incapacitated due to vaccination. Many countries do not even have the 48 hour grounding requirement the FAA imposed and you can get jabbed and go flying immediately after. What the affidavit effectively says is something that has no real chance of happening which is mild in most of those cases and can be fixed with simple medical intervention should ground all pilots. Yet everyday thousands of pilots fly with undiagnosed heart conditions from genetics and are not required to get any further testing until symptomatic, which could mean 5 minutes before you die. BTW I'm not saying it's necessary for the testing, just more likely.
