Not a presidential appointment, not even a presidential nomination. Bankruptcy judges are selected by judges already in the federal court system. 28 USC 152 - Appointment of bankruptcy judges.
As a group, judges are one of the most hostile toward the right to keep and bear arms, and judges (as a group) are also blatantly dishonest in rendering their decisions and opinions. But, even though they are as corrupt as the Mafia, they are also as powerful.
Thanks for the clarification on the selection method. You’re quite right about the judiciary, one reason why they need to be made far more accountable for their actions (and that there should be avenues to overturn their blatantly unconstitutional rulings when necessary).
