Also there's been evidence in the game alone that Miqo'te, particularly the Keepers, are avid hunters so it's not really hard to figure out. Don't rely on the race description alone because you can find more in-game.
Besides, the Xaela lore in-game is so non-existent, I have to admit.
I doubt most people actually pick a race from their lore alone, and not from how they look like. I know I didn't.
If the people who apparently play Xaela hate their own clan then they shouldn't be playing that clan in the first place, really. That's just inadequate evidence if you've talked to only apparently "a lot" of people. To prove
my point right, it's the high population of Au Ra itself.
