Which one do you mean by “the denial argument”? (and why do you use that term instead of something unambiguous like “lab leak” or “zoonotic origin” hypotheses?

Which one do you mean by “the denial argument”? (and why do you use that term instead of something unambiguous like “lab leak” or “zoonotic origin” hypotheses?) As to which of the two hypotheses is more predicated on politics, I think there are more generally left-leaning people who are swayed by the lab leak (circumstantial) evidence, than there are right-leaning people who are swayed by the zoonotic origin (circumstantial) evidence. This perception may be mistaken, but assuming I’m correct, this would suggest that the zoonotic origin hypothesis is more likely to be predicated on politics. Edit: typo
