You know, I never really had much interest in Brevoy because it was the "OMG Game of Thrones" region of Golarion, and I'm the only person on the planet who doesn't like Game of Thrones. But if this is really what the Aldori swordlords are like, I might have to rethink that.
I was making a Brevoyian dexterity fighter, and was trying to come up with reasons she wouldn't just go with the Aldori's. As I couldn't find anything about them being more inclusive than the name indicated (all I had at the time was the World Guide), I decided it was one of the many reasons she dislikes them.
Wanting to use her Elven Curved Blade instead of the Aldori swords would have kept her out anyways, but she keeps blaming them when it's really just her stubbornness. Also dislikes Dawnflower Dervishes because she's a Dervish Dancer of Brevoyian music and thinks it's superior. She's rather ... judgmental.
