I’ll be honest I don’t view demons as races. They are monsters. You don’t say the race of griffons or the race of black puddings.Exactly. In other words, race is one of the very few identifiers where you know if you can kill without hesitation. I'm glad you see that your statement that race is irrelevant was incorrect.
Consider it a amendment to my statement not a repudiation of it. Regarding sentient creatures not inimicable to human life, like the example of goblins given in this thread, I do consider race irrelevant.
