I think it's a sign of a quality mind not to be so sure of itself. A lot of the dogmatic people are full of **** anyway.
Just make sure you are changing your views with reason and not just surrendering to someone else's preaching because you're intimidated.
But, yeah, as far as contemporary stuff goes, I tend to stay out of it. There's way too much information out there and unless you're willing to narrow your focus and specialize in a certain area, it's hard to have anything but a shallow understanding. Anyone who gives off omniscient vibes is just posturing.
There's a reason you see professors of history encompassing a specific period, or experts in foreign affairs with certain cultures/regions. It takes an enormous amount of dedication to form a 'educated' opinion about something. And even then, I'm sure you can find contradictory points of view from someone else in the same field.
Never could learn to drink that blood
And call it wine,
Never could learn to hold you, love,
And call you mine.
