Not all Enclave are the same. East coast with the president wanted the right thing.
The COL Autumn was the asshole.
Enclave deserve an actual story
Oh, the Enclave do have a story, just not one that makes them hero's or patriots.
The are the decents of traitors who, instead of trying to help rebuild the US after the war, were content to simply try to hide in the oil rig and the few small mainland bases.
House is more of a hero than the Enclave, and frankly the only reason the Enclave has their nice gear now is because House controlled RobCo before the war and made most of it for them. Heck, House tried to get the pre-War gov to adapt his ABM tech, and they seemed to have ignored him out of arrogance. I mean, if even a 1/4 of the pre-war Us the Enclave claims to represent had the same tech as Vegas, the country would likely have remained a functional entity. Like, when Vegas has a better ABM shield the DC, somethings fucked up. And the Zetans never got into House's shit, either his computers or into Vegas itself.
The Enclave never made any attempt to say, aid the Followers of the Apocalypse (Arcade was helping them in exchange for hiding in their ranks, even if they may not have known about his background), who actually attempted to make the wasteland better for charitable reasons and would have welcomed something resembling an legit successor org to the US Federal gov.
And the FEV/modified FEV is the real cherry on top. It's pre-war existence is why there is a BoS to begin with, and when the Enclave found Mariposa and decided to try to make another round of FEV, they showed they were genocidal madmen. Autumn wanted to use the Purifier to spread his own bit round of FEV covertly, which is still genocidal.
Just because they painted the Stars and Strips on their power armor does not remove the fact that the Enclave is led by genocidal assholes, and filled with people ok with following genocidal assholes, so long as they claim to represent the remnant of the pre-war gov.
The Enclave is evil, and no cool graphics or patriotic paintjobs will change that.
