I drew the real life parallel because you mentioned not being so bothered by Solas attitude because you don't agree with IB views on the Qun. But I guess we are going around in circles now and we'll have to agree to disagree
Always great to read other opinions, it really makes you think over your own.
Changing subject: I find interesting this new approach that maybe Fen'Harel didn't free the slaves; perhaps with the gods locked away and out of contact, the elvhen society crumbled on itself and with the old structures gone, there was nothing binding the slaves to their masters. Which in turn makes me wonder how extended slavery was. All members of society were bound to each other in varying degrees according to a hierarchy? There was only an enslaved class which performed the most menial tasks, much as city elves in modern Thedas? Were there different types of slaves with different status, and for instance someone like Abelas had a higher status than a servant? Questions, questions.
I have one more question that I'm asking myself for my next drawing and I'd like to hear your opinion: did the gods have some kind of facial tattoo or paint, or do you think it was so associated to slavery that they would never think of it?
Fair enough, I don't think I'm entirely expressing myself properly so perhaps it's that, but I agree let's leave it there. 
There was a fanfic I read (the only one I had the courage to read and it was an AU), I can't remember what it was called but it was linked here at one point. Anyway, it was basically set in Fen'Harel's days and with him going around with a Lavellan and doing little missions to free pockets of slaves from under their masters. Fen'Harel essentially using his abilities to remove the Vallaslin and thus this somehow freed the elves from their masters.
I loved the writing but I couldn't finish it, purely because I can't see Fen'Harel/Solas making his rebellion that way. I see him more as a "big picture" guy, and would make one big move in secrecy to bring down the elven Gods. He does, he seals them away, but makes no mention to the slaves themselves.
One day they're fighting amongst themselves in the names of their Gods, the next their Gods are gone. Not all of them were unwilling slaves, surely. Some must have believed in their cause, their fighting, even if it was only for the vanity of their masters. So they keep fighting, somehow finding out that Fen'Harel is the one that locked away the Gods and instead of cheering, they blame him for it. And then the Tevinter come.
Does Fen'Harel realize this? Is he already asleep at this point, or is he awake long enough to realize what he's done hasn't actually solved anything. I personally would like to believe the former, but I don't know. x)
The fanfic also compared Abelas as more of a servant/bodyguard to Mythal rather than a slave too, and I think this fits him.
