On other precise notes, technically the Cult of Kilrox wouldn't be Heretics or Infidels, but Blasphemers and the same goes for the Golden Crusade.
Both gods are part of the same religion as they are part of a
pantheon of gods.
Therefore one must believe in all of the gods in order to believe in one, but however stating your God is better than another God is blasphemy against all the other gods.
So in conclusion, both groups here are Blasphemers by claiming their God is superior and insulting the other.
Making you as bad as each other.
^Denying the Godhood of Kilrox- Blasphemy
^Insulting Harateth- Blasphemy
