He was specifically referring to the world of Thedas rather than real-life, though I do completely agree with you.
In Dragon Age, we've never even seen a human/elf pairing because...let's face it, there's a lot more room that needs to be covered as far as reconciliation is concerned. I'd currently place the relationship dynamic as a comparative mix between the Jim Crow era and the Jewish Ghettos
Well it's not like interracial relationships didn't happen back then, though. They happened frequently, though perhaps not so frequently as today. They weren't (always) so open, and they were scandalous, but they happened.
Sigh your really gonna pull that card?
There is a clear difference between humans of different ethicity and two different species entirely. Humans have been on top since they destoyed Arlathan and they have no respect for elves unless they are grey wardens. And even then they don't see an elf, they see a grey warden as Garahel and the elven HOF have proven.
Yes, I'm going to play that card, because it's applicable. Elves are used as a cipher for oppressed cultures in the real world(dalish are analogues for the roma, city elves for jews). Their situation is meant to reflect that of real world ethnic groups who've been treated as something other than and less than human throughout history.
Saying interracial relationships between elves and humans is "wrong" is no different than saying interracial relationships in real life is wrong.
