The fact is that calling the U.S. McCarthyist is a wild exaggeration, but calling China a repressive communist regime is totally accurate. Perspective... do you have any?
As for the accusation of "wild" exaggeration; granted, it's an exaggeration, and I should probably stop rabble-rousing someday. Still, nationalistic prejudice? Check. Paranoiac delusions of espionage/propaganda? Check. Lack of any reasonable oversight such as, you know, asking NASA by the phone? Check. Harassment of foreign nationals? Check. If anything is lacking, is scale.
