This is complete bull. He brought up the Order justifiably because the historical accuracy argument was specifically used on NeoGAF quite prolifically in the defense of the game not including minority characters as if their existence would disrupt the plot more than the magical werewolves running around in the game. Some people disagree with using the Order as an example because a few minority characters exist in the game that are important to the plot. That doesn't excuse bad representation, but now everyone is focused on bashing the OP for including the Order as an example rather than actually discussing the very issue the thread is concerning.
Whether you consciously realize this or not, what you and others are doing is a technique known as FUD. Rather than actually facing the issue at hand and grapple with the ramifications brought up in the article OP has linked, you're changing the discourse to only focus on the Order being used as an example and claiming that its inclusion proves everything else he has said is wrong. This is ignorant at best, and completely disingenuous at worst.
You can call it FUD and I can call it holding people who I agree with to a higher standard. I actually fully agree with the larger point, but disagreed with the basis for reaching that larger point. That same basis caused a separate argument that could've been avoided entirely if it was sound. Maybe you think it's profane that I'm not the tip of the spear and have the nerve to criticize this argument, but I'm ok with that.
This discourse was already derailed. That was the problem with the argument. I came nowhere near saying the premise invalidated his larger point, I clearly said it needlessly distracted from it. The bolded is what's ignorant at best and completely disingenuous at worst.
