There are several articles on this site about coronavirus and the logistics that are relevant for its spread/containment. Why is this the only one that has generated rightful rebuke? It is because it is filled with subjective biases that do not form proper logic. Correlation is not an indication of causation, let alone sprinkling sanctimonious platitudes and responses feigned as nuanced discourse. You are making a quantum leap that is quite disingenuous. Just because most people eat ice cream in the summer, and most murders occur in the summer, it would be improper to conclude that ice cream causes increased murders. The priggish author went to Beijing and Shanghai, then makes conclusions about Wuhang in a country of 2 billion people. It is akin to a foreigner visiting Flint, Michigan and observing impurities in tap water, then concluding that intellectual disabilities in America are a result of poor drainage systems. IF a=b, and b=c, then a must be c is the foundation of illogical fallacies. Again, why do you think that this article out the several written (written by more qualified authors) on AN elicited the response it has? Perhaps it is because it has inflammatory language and unsubstantiated anecdotes improperly generalized to a bigger population.
Speaking of McCarthyism, here's a poignant quote from a man who endured the worst of McCarthyism's fear-mongering propaganda based on meaningless innuendos and platitudes: “History will have to record that the greatest tragedy of this period of social transition was not the strident clamor of the bad people, but the appalling silence of the good people.” ― Martin Luther King Jr.
