Perhaps you could enumerate the facts relating to the lab leak theory? All I have is:

1) A virus research lab was located in an area where novel viruses have tended to emerge.

There are several issues with the lab leak theory:

1) Creates a target for (racial?) hatred and blame - i.e the Chinese.

2) Absolves us from blame, 'a few bad people' (like in the movies), instead of general human encroachment on the natural environment.

3) Feeds the anti-science narrative.
