I was being sarcastic
The Brotherhood used to be the closest thing to "The Good guys" in the fallout universe.
Fallout 4 is probably the most Rinkydink the Brotherhood of steel ever got. For a while I kind of wondered if they really were brotherhood of steel and that maybe it is a twist and there are no BOS here and they are basically pretending to be for legitimacy.
I am willing to forgive Bethesda's take on BOS because it's happening on the east coast (an entire friggin continental US away from the previous games) and the Eastern BOS rebelled against the Western BOS' principles. They are, for all intents and purposes, an entirely new faction that has nothing to do with the Western BOS apart from the name, rank structure (which is not completely the same, IIRC) and raging hard-ons for power armor.
Having established that the core principles of the BOS can be changed coupled with what I assume was a particularly nasty conflict with the Outcasts and continued fighting against the supermutants of the Capital Wasteland could lead to rapid militarization and willingness to include outsiders into their ranks and a xenophobic attitude towards non-humans (although I suspect the latter . Especially if under the leadership of someone younger and more willing to bend the aforementioned principles to suit their own needs and desires, i.e. Elder Maxson. So that part I can rationalize. Which isn't to say they make sense.
Hell, it's made plenty apparent in their story that the whole Commonwealth Expedition is basically a poorly-rationalized excuse to expand their territory and get their grubby hands on some immensely powerful technology.
Which makes the whole "NUKE TEH INSTITUTE" ending that much more dumb when you get the feeling that their entire questline is going to end with the BOS claiming the institute as their own turf and keeping the tech for themselves, to further cement their status as the most powerful faction in the area. But no, apparently the "I just want to protect the people from horrible technology" demagoguery Maxson has going on is actually his honest belief. Which kinda shifts his character from "brilliant dictator" to "poorly written" in my book.
I just wish Bethesda stopped calling them the Brotherhood of Steel and renamed them to something different because honestly, they really are a totally different thing to the western BOS of the original games and NV.
Speaking of factions and such, does anyone else find it hard to believe that in 200 goddamn years the only faction on the east coast that has developed to the point in which it might be a large political entity, capable of fielding armies of conquest is the Eastern BOS?
Everyone else seems stuck at city state level. I mean you'd expect at least some semblance of nations forming. Alliances between cities blossoming into more permanent affairs and the like. Large scale trading and manufacturing operations and so on. But nope, everything is ancient greece and cities are as big as we're going to get I guess.
