To be honest, I didn't even think there were legitimate voices saying that Xi demanded the release of this virus on his people knowing it would eventually target the US. Even early on when it was tough to even say 'lab leak' without looking like a tin hat, everything I saw was in regards to someone in the lab getting it on accident and spreading it unknowingly.
But to some, if it's important to lay the blame on Trump before they will go the route of accepting even the option that this was lab leak, I may not understand that, but go for it.
To me the origin was important if it was out of the lab. And honestly at this point, confirming that doesn't matter as long as all people realize it definitely could have come from the lab. The reason I believe it's important can be summed up by re-reading your first paragraph from the post I responded to. Better administration is needed to either ensure it doesn't happen again or even if it didn't happen this way, to help ensure it won't in the future either.
