We’re likely only seeing a small part of what’s actually happening in her life. She was married off at 20 to a predator. She stood by him through the Ashley Madison scandal and now through this situation as well. She’s living in a house owned by Jim‑Bob and running a large‑scale dog‑breeding operation just to support her family while her husband is in jail.
Her father is a hillbilly halfwit & absolutely a wrongun. He's a dollar store JimBob. He & his glazed-eyed wife were definitely on the wrong side of the tracks at the IBLP buy-bull camps the Duggars used to swan about at.
Anna's old man is a self taught fire & brimstone preacher whose "ministry" is primarily to sex offenders in Florida state prisons. In return for which he gets a small stipend from the Dept. of Corrections.
Which the Dept. in its turn passes off as "Inmate welfare" in the budget allocations & washes its hands of the entire subject.
Josh was married off to Anna in the wake of him being reported for the sexual assaults on children including his sisters. Because none of the more affluent IBLP families wanted to hand a daughter over to the doughy pervert. Anna's old man didn't even haggle I reckon. Just took the first offer & shoved her in the path of that monstrous bastard to use as his wank sock.
