Whether COVID came from a lab or not is only of tangential importance. If you have a system in place, it will get breached eventually. Forever and always. It's China. Nobody else is responsible for China.
What is VASTLY more significant, and where most of the debate is centered, is how we responded to the fact that a deadly virus was spreading. The terms "Wuhan-flu," "kung-flu" and "China virus" were direct attempts by political leaders to deflect the responsibility for their lack of action and failure to mitigate the affects of the virus.
Hell, it's a lesson even a child should know: you are not always responsible for the situation you're in whether that's a kid picking on you or COVID, but you are fully responsible for your reaction. My son's favorite word right now is "well...." because as very bright 8 year old, he wants to discuss his reasoning process with me to justify why he acted the way he did. And mine is "well, nothing..." because most of the time when we have these incidents, his reaction is out of step with how we've taught him to behave in the situation.
The political arm of the Trump administration was FULL of "well..." instead of addressing the issue, and the political polarization of the US has allowed a big percentage of the population to justify their own responses to mitigation efforts in the same manner. Because most adults have gotten there by reaching a certain age, not by reaching maturity.
I remember watching in horror as the US was shutting down its borders because the virus had spread to Europe, but people were packed into our major international airports like sardines and remained there for hours. It was and is incredibly stupid and irresponsible.
