Lex Stop! Please Stop trying to find a reasonable justification for Prof. Colin's or his email. He was demanding Dr. Fauci to basically destroy the reputations of these scientists not to disprove their premise. Just because he is a preeminent geneticist who did great things does not absolve him from the human condition of greed, arrogance, narcissism, etc... But as you said good humans try their best to overcome these failings.  Also, do keep in mind Collins is not a benevolent benefactor to science or scientists. The funds he disseminates are not his own but paid by taxpayers and the scientists and projects he selects are again subject to the same human deficiencies he has amply displayed.
