In the case of covid there seemed to be universal belief in the media that covid originated in animals. There was no proof of this claim.
It’s one thing to just simply pick a claim and believe in it. It’s quite another to attack people who are providing an alternative claim.
The same thing rings true with regard to what is a “correct” thing to say. “China Virus” is apparently repugnant. However, naming the country of origin for variants is not. South African Variant is fine.
