This reminds me of Upton Sinclair's reaction to the reception for his book "The Jungle".
Sinclair was a socialist and thought that if he wrote about how the workers in America at the time were mistreated, and their terrible lives as a result, that he would rationally persuade people to champion the cause of workers' rights.
Instead, he got people in the stomach, with his depictions of all the craziness that went on in how food was produced in America at the time (with no regulatory oversight or any general laws on untainted food), and the result was the passage of the Meat Inspection Act and the Pure Food and Drug Act.
Or like the way that Al Capone was brought down - not for illegal activities per se, but for failing to report the income he derived from his activities, legal as well as illegal.
If Fauci gets brought down because of the animals, so be it. One way or the other.
The only thing to keep in mind, however, is that a lot of things are tested on animals, and this may be the camel's nose in the tent for groups like PETA.
