I think many in this thread do understand that Sera looks from the perspective of the masses. I am pretty sure Friends of Red Jenny is a reference to Anonymous. Sera is you and I.
And Sera is religious without questioning why, afraid of magic because it is dangerous and different, incomplete in her education because there was no public education system to offer one, and uncomfortable with her own ears because she grew up amongst people who looked down on her for them. She views the world with a simple but effective lens, and rages hopelessly at a system she cannot dislodge despite her best efforts (Until she joined with people who are not commoners, people with power who can "decide what is best for Thedas").
The nobilities of Thedas as assholes, and they were born into the perfect circumstances to become assholes. The commoners of Thedas are not without many issues of their own, and they too were born into horrible circumstances that shaped them. Remember what Vivienne was afraid of should the circles be abolished? The lynch mobs of falsely accused abominations made by the very common masses. Remember what happened to Minaeve when she was first chased out by her clan as a little girl? A lynch mob.
Overall Thedas is not, and was never meant to be a nice place. It is a sickened planet filled with many struggling societies, from the top to the bottom. Are all these people to be blamed? Not really. Are they often times right when given the consideration of what sort of world they must survive? Yes. Do I want to live there even without magic and darkspawns? Hell no.
