Why are so many players siding with BoS in the play throughs?

It’s a genuine question I have with FO4. I’m still debating which faction I will go with, but so far all my interactions with BoS outside of dealing with the companion just annoyed the heck out of me. Their “true saviors of humanity” approach just rubs me the wrong way and that’s before you take into account their views on ghouls and synthetics.

Also, can I get shot for insubordination since I chose to interact with every BoS NPC using Sarcasm option?

EDIT: Holy crap, I did not expect this to gather this much attention since most my posts usually don't. I appreaciate everyones input and enjoyed few discussions I had, but I just can't keep up with it so I will just try to address the general patterns I noticed. It seems that the opinions on the matter fall into a following few groups:

  1. Second/Third play through, "evil" run, trying to get the most out of the game: I trully wish I had the time/dedication to play a game more than once. With the general responsibilities and the game backlog I got, I have some games that I bought years ago and have not got around to play yet so I generally just try to run games with builds/decisions that most appeal to my personal morals. But definitely cudos to those of you who can. Honestly, I might make an exception in FO4 case and maybe have a save file prior to where you have to make an event horizon decision so I can see all the possible endings from that point on.

  2. Cool tech available early in the game and some features that make late game/survival game a lot more tolerable: I can definitely get behind that. Sometimes it's not about morality, but just having funs shooting the most eminies with the biggest guns available. And playing FO wihtout access to fast travel would definitely feel like a slog to me. There is only so many times I can walk through bombed out Cambridge getting annoyed by the raiders attempts to kill me before I call it a day out of boredom.

  3. Roleplaying as a character based on the miniscule infomation we know about his/her background: I get that, I guess. It's not for me, but I get that. Personally, I tend to insert myself into the role of the character rather than trying to guess characted motives, so I roleplay as an agrieved father on a path of revenge/recovery. The way I see it, I wake up in what used to be my home city and everyone with guns is trying to kill me now with a small exception. There are Gunners who wear matching uniforms, take slaves, and shoot at me on sight. I am even hunted by the Enclave who are the closest to the military org I serverd with before the war. All of a sudden a well equipped force rolls up and makes themselved at home in my city. I sure as hell not going up to meet with thier commanders in the middle of their encampment surrounded by their troops armed to the teeth until I know everything there is to know about them. And once I figure out that they are a threat to those few of the companions I met so far that are not trying to kill me, I doubt I will be going to meet with them at all.

  4. Those who genuinely agree with BoS views: I don't know what to tell you. You do you, I guess.
