Actually it's because some NCR supporters that are ignorant to Legion lore start dissing on them and no matter how many facts we present to prove them otherwise they still go "lol, Legion are slaver tribals with machetes also evil!"
Notice I said "some", not all, some NCR supporters can present good cases and accept Legion lore but the one's who fuel the fire are those ignorant to it and some of the Legion supporters that keep arguing with them despite that it's been proven several dozen times before that they won't budge.

So I would not say that it's us Legion supporters who start the fire by mocking NCR supporters opinion.
It's the other way around, it's almost always the other way around...
I wonder when the first "I think Legion is better because of blablabla", "Legion are just a bunch of backwards tribals with machetes!" is gonna come. :rolleyes:
And like I said in the previous thread, I'm gonna try to stay out of it.

[edit]
I'm not saying that us Legion supporters has never been the one to start the fire but it's far more often the anti-Legion bias starts it.
I'm also not saying they are the only ones to blame, us Legion supporters are very good at throwing logs on the fire once started.
But it's sad really, either we let the anti-Legion bias continue without ever defending Legion or the thread(s) derail like so many has before. :confused:

Anyway, back on topic:
If the Courier died then House would have had to find a new monkey to do his work or storm The Tops for Benny, Benny would escape and land in Caesars lap.
So if House cannot find a new demi-god then he's screwed, Benny is also screwed, and considering the railway bombing, The Divide, the bad supply line for NCR, Searchlight, Nelson, Charlie, better morals and equipment and training in Legion and Nipton I'd say there are several point in favor of Legion being the top dogs (despite their crap gameplay balance).
