"All men are the work of the Maker's Hands
From the lowest slaves
To the highest kings
Those who bring harm
Without provocation to the least of His children
Are hated and accursed by the Maker."
So if you tried to argue that "All men were created equal" it does not go against the belief in the Maker. Not equal in status but equal under the law of the Maker.
True- and I've always argued how interesting it is that this, from the Chantry, is the only widely accepted cultural basis of equality politics in Thedas. Anti-Chantry advocates and factions are arguing against the one standing political equality foundation of the setting... and without that illogical religion, arguments that people with magic resistance are equal in creation to people without it are equal to people who can make fireballs with their minds are a bit less convincing.
The fall of Andrastianism would probably lead to the loss of what progressive values Thedas has, not promote their rise.
No wonder the nobles don't want any commoners, human or elf, to get an education. The consequences for them would be terrifying.
Eh, if there's one thing the 20th century demonstrated it was that even an educated populace can be led to terrible things. And it's definitely not clear that education would promote peaceful conflict resolution.
Take Dalish-Human coexistence, for example. If, say, education taught a systematic review of dalish infractions and crimes against humans that would otherwise be forgotten to history, as well as the darker aspects of ancient elven culture (from the mageocracy to implied serfdom to the possible blood magic rituals for immortality), Human tolerance for the Dalish could drop dramatically.
Of you could get radical reformers who do believe elves and humans should integrate... but then look at the math of what it means in terms of breeding, view the inevitable breeding out of the elven race an inevitable consequence of the progressive future, and decide to helpfully accelerate that to get to that better future faster.
Or consider what an well-educated security state aparatus would view and do with mages. Anyone who thinks the Templars are horrible would find them quaint and old fashioned compared to what a professional and competent security state analogous to, say, the Russians would do.
