Are there any other Theodosian groups that we hate besides Orlesians?
I understand that some people aren't fond of Tevinter, though I can't possibly fathom why. Blood magic and slavery are so in this year!
The Dog Lords of Ferelden can't possibly be hated. They're called Dog Lords.
Kirkwall is...is Kirkwall.
And I know I've seen a few with hatred for the Qunari. Like, say, Solas. 
The Qunari are despicable, but I admire their strength and iron will.... would kill them without hesitation, but I can't muster hate for them. Tevinter are pretty much Orlesians, except magic... Great oversimplification I know, but basically. Terrible outfits, self important snobs, Great douchebags, etc.
But the reason I dislike the Orlesians above all is because they have the nerve to pretend like they're anything but the little **** heads they are. Especially the Chevalier... And all their stupid pointless parties meant to make themselves feel even more important... It's no wonder Leliana enjoyed "The Game".
And I hate hearing that crap. "The Game". It's so corny.
