Never did I state the Alliance was good. However the Horde is magnitudes worse, and what you listed pales in comparison to the list of atrocities the Horde committed. ESPECIALLY if you want to start playing genocide olympics, the Orcs are undisputed world champions.
Also ‘‘Jaina tried to destroyed Orgrimmar’’ (Let’s not mention that it was in response to the Horde literally wiping Theramore off the map, oh, and they ACTUALLY DID IT, unlike Jaina.)
