Oh, that.
Well, the comment I replied to mentioned curbing the excessive xenophobia and portrayed half-elves as a result of this; I may have misunderstood which part you object to. Now with so many occasions of having had to fight together, it would only be reasonable that races learn to coexist. Half-elves... I guess it would nice to keep them rare in the lore, but I don't think they are inherently wrong. There had been half-elves going way back; Alodi was one, if I recall correctly.
