But you are admitting you are calling it "The China Virus" as an attack on China.
That was the whole point of people starting to call it that in the first place. No one pretended otherwise.
COVID-19 was used very early. Only later, because people were mad at China and wanted to attack it, people started calling it the China virus.
There is no other reason people use the term. Even you, right now, are saying it you use it for that reason specifically.
All these defenses about how "well we call other things by their region, and we are doing that with the variants" is a smokescreen, which you yourself admit.
People assume if you are using "China Virus" it is racist because the only reason people use it is to attack China. You can make the argument that you are attacking the government and not the people and there is some legitimacy in that argument, but "I'm going to use this thing racists use because I, too, am mad at China" isn't really a strong defense.
I fully expect people to start referring to the "Wuhan variant" along with the other variants at some point and it won't be racist because it will have come from a different place.
