I like the feeling/thought of being among people that live, or try to live, or at least know they ought to live by higher standards of conduct (maybe it is just what I'm used to...)
I'd venture to say most people who voluntarily choose to be dubs think so too. It has to do with personality type.
Take this test. You will probably get a J as your last letter. At the end of the test, it will explain the J and other letters. Again I'd guess most dubs are too.
I've taken every hokey pop psychology personality test out there (due to the profession I'm in), but this is the only one that holds water. And when I got the results and started learning more about it, it was just light turning a light bulb on. It explained so much, what was naturally me and what was a product of dubbery. It helped me understand my authentic self.
And then once I did, I understood some of the adjustment difficulties I had post-Borg. Some of that is me and there's nothing wrong with it. And some of it needs to give the rest of the world a break. I am not perfect either.
Try to spend time listening to people from all walks of life, those who are different from you. Ask them a lot of questions about themselves, and try to imagine things from their points of view.
