I'm not sure whether you're upset about something you can't change, or just misunderstanding.
It doesn't matter what Mendicant is, does, or says; it won't change the fact that he and Aurvandil have become a unifying common enemy for at least much of Sanguis Astroism. This is something that it's probably too late to change by any one person or small group; it's just become part of the common culture/mindset of SA.
The term is indifferent, not upset.
Sanguis Astroism can believe whatever they like, Mendicant just declines to be their next Haruka.
