For the last 20-30 years, the AF Academy has been co-opted by a religious cult called the Dominionists.
They basically believe in a religious theocracy with themselves in power.
It's also almost impossible to make General without being an Academy grad. Partially because officers who make General have to be set up for that career path as Lieutenants.
The MRFF was actually created explicitly to fight against dominionism and similar creeds. The Republicans of the House slipped an amendment into the upcoming Defense budget that bans military members from speaking to anyone associated with the MRFF.
