This isn't a both sides situation. There was no science indicating that the virus was leaked from a lab.

One side said "the virus was leaked from a lab! we should call it Kung Flu or The China Virus!" and the other side said "there is no evidence that the virus was leaked from a lab".

They're not equal and opposite positions. One was kneejerk and unsubstantiated, the other was scientific.

I'm certain there were some people out there who took the lack of evidence as proof that it wasn't, but those people were wrong and unscientific as well.
