So someone with expertise in other non relevant fields is enough? Yet people that have expertise in relevant fields dispute his conclusions and its not relevant somehow?
Not your credentials specifically, but Steven Quay. Cursory search suggest he's not an expert in relevant fields, but does have a book about lab leak theory. Immediately suspicious as there are a lot of scientists that turn to grifting in areas that were not relevant to their expertise.
I don't much care what the man does with his free time. I'm more interested in the veracity of his statements. On that front he supplies copious references to peer reviewed research by numerous others and primary sources. Character assassination is for folks who can't argue on the merits.
Not a word yet about your motivation. Huh. You'd think anyone out here demanding others' credentials would lead by presenting their own.
