From your tactless use of slurs, it's pretty clear that you wouldn't recognise tolerance if it smacked you in the face, but just because a society is intolerant in some areas doesn't mean it can't be tolerant in others. Our modern society still sees different levels of tolerance and intolerance for different groups.
Nobody is accusing fictional characters of being intolerant. If there are any accusations of intolerance in Dragon Age, and I haven't seen any, they would be levied at the creators, because they are the ones responsible for any intolerant messages.
You know what's really ridiculous? Talking about medieval attitudes in a fantasy world.
Yes, the Western World has a history of homophobia. But the Western World is not the only society that exists in reality, nevermind in fiction, and not all societies develop along the same trajectory. You might be incapable of conceiving of societies that develop a concept of tolerance earlier than your own did, but conceiving of societies that differ drastically from their own personal experience is pretty much the entire job of a fantasy author.
What does "tolerance" mean in your world? I am neither a Nazi, nor a religous fanatist and whatever sexual orientation you got, feel free to live it - i don't mind.
All i wanted to mention is, that i don't see how his "idea" would fit into any kind of society which reflects aspects of medieval reality. Thedas - as it was expressed in DAO and DA2 is no gene-roddenberry-star-trek-like universe where -astonishingly- 90% of humanity is so good hearted that it begs the question, why all those wars in the past?
Thedas is a world of extremes , of strict social paradigms and his idea of an evolved sexual attitude would just not FIT in! Like: Boy, i don't care if you're into men or women, but don't even dare to vring an elf, dwarf or mage home!" Can't you SEE the point? Or are you just one of those oporutnists that have NO idea about the true face of Hmanity and society.
If so, don't call anyone "intolerant" just because he's disillisioned, realistic and maybe a bit cynic.
