When you were ethnically cleansing the ogres who dared to challenge slavery, you end up killing a lightbound ambassador who was having a meeting with the ogre revolutionary leader at the time.
The army is then called in immediately after. kill a an american ambassador in the name of your racial pride and you would get american marines on your doorstep within the day.
When the dranei army arrive, they say their beef with the orcs is the orcs killing the planet, and would be willing to work with them if they put down their arms.
Keep in mind I actually played this scenario and read all the quest/flavor text. I heard the same rhetoric you are spewing now and so I paid extra close attention to what was happening. All of you are full of it.
Not even the orcs say that. They just say the converts are brainwashed, implying that there is no way they would ever “betray” their precious master race otherwise by becoming civilized.
I am talking about actual in-game actions, not memes surrounding the scenario or you falling for in-game rhetoric and ignoring in game actions. Ironically, you are proving my point that the playerbase just goes by whatever in-game characters say as if they are all perfectly honest.
