Well, not pretending to have all the answers might be odd, but it's pretty sensible to me. I run across a lot of people who have opinions on all sorts of stuff, nevermind that on at least half the subjects they have no expertise, education, or experience. I have made it a personal goal to avoid that particular human flaw--and it is a flaw.
That's not to say I have no opinions on anything. It's just to say that on some things, say, foreign trade agreements, monetary policy, banking regulations, insurance law, Senate ethics, just to name some off the top of my head, I may not know what I am talking about, or I may be wrong. If that's odd, so be it. In fact, I suspect if folks generally limited their opinions to things on which they have some experience, expertise, or education, we'd all be better off. After all, the Constitution was not drafted by rank amateurs. But hey, what do I know?
