You said it before I said it.
There are some good things in PFAL, but that's because they were pinched from someone who'd put thought in, and who may himself have been inspired by God.
Also some good things in the RHST part - for the same reason.
The trouble is trying to sort out the truth from the fanciful, reconciling the conflicting messages and versions of whatever "the class" says, etc. Not being able to sort out truth from - from what isn't - is confusing and distracting. It's a poisoned apple (from a poisoned tree). Not all of the apple is poisoned, but you don't know which bits are and which bits are safe to eat. Best thing to do is discard the lot.
Heck, for all I know, the confusing bits were deliberate - to confuse, to distract, from the other garbage that we were supposed to take in subliminally. If you're still trying to reconcile "all without exception" with "all with (or without) distinction," you're missing some other perhaps more serious junk.
