I simply don't understand why you are so defensive about it.
Because you stated false, ignorant, and woefully wrong evaluations as fact of a profession and course of study. (This is called lying. They teach us not to do it in our classes. Don't they teach you not to do it in law school?). I dislike lies, mistruths, and misrepresentations. It not only is sloppy thinking, but is an insult to much of a course of study I respect. Your off-hand statements were patently false and were obviously made due to a personal bias.
Furthermore, Business is not some "inborn" talent like perfect pitch. Businessmen are self-made, not born. Good businessmen learn the same subjects whether or not they attend business school. They don't just magically appear. And your assertion is yet again a biased dismissal of business as a legitimate and rigorous course of study. Wonder why you have such animus against it?
Statements like yours are insulting to my profession, they are based on nothing factual, and they are common among those who have no exposure to business school curricula.
In short, I dislike people lying about things of which they have no clue. Hope that explains things better for you.
Thanks for your opinion.
