The other thing I'd like to say is that genuinely intelligent people don't speak like you. I have a good degree, I have business successes, both for global businesses and my own startups and I class myself as fairly intelligent.
I've also worked with (and happy to call my friends) some truly fantastic brains (who have elevated my own personal performance over the years). Not one of them has acted like you are doing on this board, they have tended to be humble and educated in what they do and how they discuss it. The people who act like you tend to be the charlatans in the business world, that stamp their feet in meetings and try to shut down debate because they aren't capable of contributing to it in a constructive way.
