Per the Bark, not the helpfile, certain things are pretty unpleasant. While an AP or otherwise can abandon their spells/communes and live like a rager, racial limitations can't exactly do that.

Bark citation:

III. Endure Not That Which Offends Her
Necromantic and demonic sorcery, minotaurs, orcs, goblins, and all other aberrations to the land and nature are NOT TO BE TOLERATED IN ANY CAPACITY.



Assuming we go by that, the hard no is racially pretty clear.

Open minds are neat, but they have at least SOME restrictions. There are "hard no" spots in multiple areas, this cabal in specific happens to be a bit more focused on race than others. And nothing wrong with advocating! Conversation is how we figure stuff out :).
