@MWZ (I can't seem to carry quotes for some reason):
I would say that slavery, radical misogyny, destruction of the family unit, and intercourse (interaction with adjacent societies/communities) via atrocity is something one might consider inherently wrong, no matter one's worldview; lest one actually be in possession of a fondness for totalitarianism or think totalitarianism the most effective form of State. Now, do these "activities" have purpose in Legion society?...sure they do. Are they effective?...debatable. That would depend upon the agreement of the assumptions that opposing sides of the argument can actually agree are valid. I would say they are effective...as far as the Legion is concerned.
That doesn't for an instance, give them a pass for the commission of atrocities. One cannot just hand wave away the Legion's lesser actions away. These are the exact things that bring their overarching philosophy into immediate question....and personally what I think the writers intended. I, for one, would have liked to have seen the Legion arc developed far more instead of having to jump through some fairly extreme hoops of rationalization to make them palatable.
That "veneer" of brutality is a bit more than a thin coating if we're to be honest. Breeding farms, slavery, destroying and torturing communities because the Legion determines they are "degenerate" (which is total hypocrisy), are exactly why the Legion fails. It makes one wonder who the F--- is the Legion to determine such things anyway? I know the answer, it's because they are stronger than most of the tribes and communities they come up against. That seems to work well with ignorant tribes. That in no way translates into them being right. They will eventually run into someone stronger. It makes them no better than the NCR. Both should be wiped out or retract back into their respective holes. But, of course, the competition for resources, and the desire to expand their respective influences will force them to meet, as is natural I suppose. Maybe we'll get lucky and they'll destroy each other, or maybe a wild card may get introduced which forces them both back into their holes.
Oh, and I would say that callous brutality is nothing alien to the Courier.
It ultimately boils down to what we get presented in the base game unfortunately that isn't much.
Despite how much folks harp on the Legion on the FO wiki a good deal of the Sawyer and Vanburen Lore ultimately is pseudo canon at best; Thus we are left with what we have in game to determine the faction for merit. Caesar argues a decent case, but his perspective comes from conquering dictator, we never see the stability of Arizona, The people living under the Legion and we don't see Flagstaff the center of their culture, their perspective.
And the Autocratic/Totalitarian Government stating ultimately isn't a negative to me at least in so far as it self, it depends upon stance and usage of that absolute power. And i ultimately give it far more slack in say a game like FO or Killzone give its more a facet required for such a society to work over say the modern age we live today where we have competing democracies, dictatorships and all spectrum of ideology through out the world. The Legion flag to me at least works on some level because they can at least to some degree achieve what they preach.
They can produce competent warriors, their society at its heart is martialism, Not mercantilism, And that perhaps is the most alien thing about the entire society its formed not around a belief of wealth, nor prestige or power but the collective. I can see where forced labor, slavery and using the female sex for breeding purposes may offend modern sensbilities, but given this is FO we are discussing we must look back and realize.
Slavery, Forced Labor and the crushing of conflicting factions are common place, Heck it took the NCR quite a while to kill Slavery in the core regions, It lingered on from FO to FO 2 and even managed to linger past that if not by much. I grant you rationalization is needed for some actions, but for others? I'd say Nipton served as an adjective lesson for three reasons, it removed threats to the Legion both in the form of criminals and NCR forces, It fostered fear within the NCR which are in the nearby proximity, showing that their hold of the region was nowhere near as complete as many people suspect, And culturally. The Legion found itself societally incompatible with Nipton and given what that town was, i can't really fault.
Would i support the measures they did offhandedly? No, But i also don't think it requires overmuch rationalization, Personally i think the Legion is a product of incomplete lore like many factions within FO, it was pushed into game with barely any confirmed lore behind it besides what was presented in the base game and we have to go by whatever obsidian deemed canon for the faction.
