Have any doctors or medical examiners who examined Marvin Hagler’s body contradicted his wife’s assertions? Presumably, she has more access to his medical history and the determination of the doctors working her husband’s case than any random Youtuber or blogger.
So why take their word (which is pure speculation without any access to medical information) over the word of the grieving widow who has access to ALL the medical information on his death?
Why is the wild and unsubstantiated Internet blogger claim more credible than the words of the man’s own wife? Is it because that wild and unsubstantiated blogger claim fits with a narrative you want badly to be true?
As does the wild and speculative words of the man's wife. So, impasse.
Which leads us back to, 'take vax = drop dead'.
At which point, common sense takes over. And you don't have to go to school for that one.
