However, the condemnation is not over the theory itself per se.
If someone had made the statement “We are not ruling out the lab leak hypothesis” I would have agreed with that position, and indeed I think many Democrat politicians and even some of the medical scientists said words to that effect.
However, asserting that it came from the lab, as many on the right did, and still do, and even implying that anyone that didn’t agree with them was covering for the CCP is incredibly irresponsible. It has contributed to hate crimes, and general misunderstandings about this virus in particular, and pandemics in general. And largely just to shift the blame for the terrible handling of the pandemic in the US.
And, despite the fact that certain circumstantial data has lent some support to this hypothesis, we’re nowhere near it being the most likely cause.
