well
Well maybe Caeser's Legion don't look like they fit.
But they fit what I have always seen as the main theme of the Fallout Series.
The Flaws of Humanity.
First a quick question. Whats more stupid?
A) Prancing about an atomic wasteland dressed as a Roman Legionaire.
or
B) Turning this thriving living planet into an atomic wasteland by launching a nuclear strike you know will be responded to in kind.(or lets just say starting an Atomic War).
You live in a post apocalyptic wasteland.
You answer a knock on your front door, to find a bunch of armed men. Armed men with their heads shaved bald, condoms glued to their heads in varying amounts (a sign of rank). They are wearing pink tutus, jack boots and have dummies on silver chains around their necks.
They say you can join us and we will feed and protect your family, because we will consider them our family too. Or you can choose not to and we will enslave you and your family and loot your house.
Looking a complete and utter tit is a small price to pay for the safety of your family, especially when it will likely make their life better aswell.
So as I said, flaws of humanity.
So ok CL is a unsubtle, over the top example of this major flaw of humanity.
Pack Mentality, Sheep syndrom, call it what you want.
It has countless examples, idiotic fashions people will buy and wear just because the guy designed/makes it said it was fashionable.

Then we have Hitler, a small psychotic midget most if not all the people on this board could beat up with a stupid moustache.
His rise to power in a truly fubared Germany and the resulting World War and Holocausts are well documented.
Do you think if he had made it law everyman over 18 most grow a moustache just like him, Germany would have thrown him out. Or would they have continued down the path now all sporting that hitlertache.
Most people would rather be with the mob led by the lunatic, than risk being considered an enemy of the Mob.
So yes the CL fit Fallout's main theme. They are an example of the lengths people will go to fit in and feel safe. The lengths people will go to be on the inside looking out.
Hell even with the massively unsubtle approach people will still miss the point, like the people who don't get why "The Aliens started the War" is completely against the theme of the games.
