Well, there are the issues with the appointment process:
- it was dishonest and unfair: the Republican senate broke their word from 2016 about Supreme Court vacancies close to an election. In doing so, they took something for themselves that they had denied to others in the past.
- it was disrespectful of authority: knowing that the Democrats are favoured to take control of the Senate and the Presidency, they rushed this through in order to undermine the new Senate's power to do the appointment.
And then there are the impacts that Barrett will have. These impacts will depend a bit on what sorts of cases come before the Supreme Court during her term, but they're likely to include impacts that go against a number of the points of the law, including "use resources wisely," "be considerate and caring," "respect myself and others," and "make the world a better place."
The conflicts between Barrett's appointment and the values expressed in the Girl Scout Law may become more obvious when you look at this one-pager that expands on what each of the points of the law mean in practice:
