Not having the information is one thing, but provided you had the information and are able to mentally process it, you absolutely are "entitled" as anyone to make such decisions. All nations (worth a damn) derive their legitimacy from the people, people
just like you. If you can't do it, you can't expect anyone else to.
That's very general and maybe not very helpful here, but I still wanted to make the point, because I think it's very tragic that we are so eager to hand off our opinions to "experts". I can accept teachers, so that ideally when they're done with me, I'm an "expert", too. But I don't trust those who would just remain as experts hovering in some vague place above you. From what I learned about life so far, those are all hacks.
And if these things are too complicated for regular citizens to understand, then they need to be made less complicated, or we need better citizens. Democracy in an industrialized world is no trivial task.
Basically, I can't know everything about everything. At some point, I have to trust others.
Yes, of course. But you still use indicators for that, yes? If you visited a new doctor, and you heard loud screams, you would slip out again. If a friend recommends a dentist and you're currently looking for a good one, you'll give the recommended one a try first, that sort of thing. I've seen doctors do shit (to others) that made me not EVER trust one blindly. I am usually lucky with mine, but I do pay attention to them, I do second-guess them, I measure up their character, how peaceful and concentrated they are, versus just loud and constantly on the move, etc. At the end of the day, nobody but my own immune system, family and friends truly care about my well-being, to the point they'd loose sleep over it.
