If you are alluding to the following:
"A nationwide travel ban from China took effect on January 31, 2020, with a few confirmed cases in the United States. This ban was only for non-U.S. citizens who had been in China within the last 14 days and were not the immediate family member of U.S. citizens or/and permanent residents."
This was not a political targeting of Chinese individuals. Stop buying into the Dim talking points.
Djokovic's case was political. He was granted an exemption, then denied do to the fear that he would pose a "bad example" to the fans. From the article:
"This was affirmed by Chief Justice Allsop, who stated that he accepted Djokovic could be seen as “an iconic sports star that is setting an example that is not ideal to be followed.
“If Mr Djokovic won the Open, as he has in the past, there is an example embedded in the Minister's reasoning that this is an example for young and not so young fans of tennis.”
I never said it was. It is a decision the U.S. made that it thought best for its own security. Australia is free to make the same kind of decision.
