Thommy H:
from which hashut has attempted to disassociate himselfI've never actually seen any evidence for this. All the canon background just says he is a "Chaos God, unique to the Chaos Dwarfs". That doesn't sound disassociated from Chaos at all.
And, even if he was disassociated from it, that'd be even more reason for him not to care. Does he claim sole province over all bulls? Is he the only one allowed to involve himself in bull-based mutations?
I'm not saying he has anything to do with minotaurs, I just can't see any reason he'd treat them as an abomination.
