I don't disagree, at the same time you're not giving much of a counterargument to the examples you brought up except saying "I don't like them saying this"
There is no counter argument to be made in that sense, one is not necessary. The victors are Americans. The critics in this example attempt to proclaim that the victors are not American due to race in order to tear down the accomplishment by the US, while pretending the US is a homogeneous white nation because that's the only way they can set up the fraudulent attack.
