There's no moral relativism involved. His position and mine is that the Horde is evil, not that there's some moral equivalence between the woman torching a city full of civilians and the people trying to stop her. Rather, that I'd sooner play the villainous side than a clone of the other one and be lectured on morality by characters who sat meekly by throughout most of these atrocities and in other cases flat out assisted with them, see Saurfang. The Horde has been compromised from the noblesavagery that whiners like @
Trassk are yearning for since Vanilla, when the Forsaken were introduced, goblins and blood elves just reinforced this.
The Horde as evil has predated and by now existed for a lot longer than the lolhonorable Horde if we combine WC1, WC2, Cata, the better part of Mists and now Legion and BFA as compared to WC3 and the non-Forsaken/blood elf/Garrosh parts of Vanilla to Wrath. I'll enjoy the two and a half patches or however long they give us of a proper Eastern Kingdoms or WC2 style Horde before they decide to shove the "Oh, the Horde is misunderstood, we dindu nuffin" bullshit down our throats again.
