"...Is it really so simple to you?" she asks, astonished. "I know only a little of 'tieflings,' and that I learned since arriving in this world, but aren't they simply born as they are? I am speaking of a demonic ritual that permanently tainted my very soul, because I foolishly believed I could fight the enemy with its own tools. Dozens of my comrades in arms turned traitor because they failed to control their taint. It is not simply racial prejudice that marks me an outsider."

She's not even offended, just bewildered. Nobody has ever spoken of her demonic features as if they simply don't matter.
