“On what level is it socially accepted to voice concerns or criticism of America?“
„Within the family“ criticism of America and/or of Americans, understood as internal debate about what America is and should become, is as old as the country itself.
In fact, a democracy as vibrant as the American is not possible without constant and intense debate about what is right, wrong, improvable in and about America.
Americans, however, are sensitive to criticism from outsiders, meaning from non-Americans, from those who are not a part of the family. If the criticism comes from Germans, then Americans can be come quite sensitive, to the point at which Germans have the impression that Americans „cannot take criticism.“
This has more to do with how Germans view the German-American relationship and how Germans communicate and voice criticism.
