Dwarves aren't cool anymore

[Psyren]

Although, to be fair, the quote was misapplied by assuming only lessons about humanity count, and ignoring the Giant saying worlds that differ from ours (dragons are not human) don't invalidate the lessons.

I didn't ignore it. In fact, OotS' dragons further prove the point - what mattered about the dragon in the story at that point was what she had in common with us, i.e. her capacity to be a devoted (and vengeful) parent. She too possessed a relatable, not-alien mindset, and that was a lesson that could be carried through to our world.

(There's also the secondary idea that alignment differences alone don't justify excessive/lethal force once a threat has been neutralized.)
