Please explain to me how position A) is more racist than position B)

A) Scientists all over the world, including Chinese, Americans, and others, made a fundamental misjudgement about the safety of the Wuhan virology lab, or perhaps viral experimentation generally, and the result was a global pandemic

Versus

B) Chinese people eating & trading wild and exotic meat unintentionally caused a global pandemic due to their consumption

Of course, neither theory is racist. That's a word that used to mean something (and I wish it still did!), but is mostly used today to shut down debate in Western countries.
