Hi! I see you're interested in the concepts of race and inherent alignement in D&D. Might I suggest these topics too?

Alignment - None/Static/Dynamic
Killing Goblin Kids ok but not Tieflings page 19 because
Racist Tropes on Drow STOP IT page 4
It came up in a number of the threads talking about our companions alignment, but I remember these three the best

If your comfortable Red Queen, would you mind elaborating on why you think being immediately hostile to goblins is bad.
Creatures can be born evil in D&D, free will isn't a given, and the heroic journey to change yourself doesn't occur immaculately.

dumb, pseudo-intellectual and polite homophobe
