Let's see so far what things they do that are outright reprehensible.
- Mages are either put to the sword or locked up in cages simply for being _born_. They don't even get the option to leave the country. I don't call that simple prejudice; I call it genocidal eugenics.
- Naysayers or free-minded people are outright forbidden in the country, more-or-less. Lux's attempts to try to be more open-minded seem to make Garen think that the Mageseekers will harm her for being a "mage-lover", so to speak.
- Even when they have evidence that their Petricite isn't actually anti-magic, they squelch the truth and would probably kill those who figure it out. It's like Diana's case only much worse.
- Arranged marriages where the daughter has absolutely no say. I've never been a fan of this.
Why, oh why, does Lux defend this way of life? Sylas might be too extreme in wanting to kill just about everybody in said society, but I don't think I'd shed any tears if Noxus were to wipe Demacia off the map (as long as Lux stayed out of the crossfire). And I sincerely hope that by the end of the comic, Lux basically leaves Demacia to more-or-less destroy itself.
