In order to get an argument going about someone else's religion or cultural matters, you generally need:
- to know about it
- to care about it
- to have contact with people who do it, and
- to feel that that raising the matter is less socially awkward/more profitable to you (in whatever way) than not raising it.
Amarrian religion scores higher on the first two points than any other set of beliefs and practices in EVE[1]. It scores well enough on the remaining points that you get your public challenges, debates, spats and shootings.
"Their beliefs are false and wrong; my religion is true and right." Whatever the particulars, this approach isn't news.
"The Amarrian god is no more than a social construct created to reinforce certain social behaviours; my people's spirituality binds us together and underpins our identity." Again, no real news there. (And yes, there's a lot you can unpack from those two phrases if you wish.)
It sounds like there's a particular combination of "you're bad; I'm good" that's irked Louella, but I'm having difficulty seeing that there's an inconsistency there, logical or psychological.
