I've been a shareholder for ~15 years, and have never been to one of the meetings. I "intend" to get to one of them in a couple of years, after my younger son has gone to college (and my wife and I can travel more freely). Those meetings sound like a fun time.
I'm disappointed in Buffet's political stances, but I can't really say anything, because he doesn't make them a Berkshire stance. And since the actual management of the subordinate companies does whatever they want, he doesn't affect those company's political stances. So...
ETA: The one thing about Buffet that really does raise my hackles, though, is his two-facedness regarding taxes. He runs Berkshire with one overarching credo: PAY NO TAXES! He doesn't sell companies in the portfolio, he configures everything to put off taxes as long as possible. IOW, he really understands how debilitating taxes are. He even takes a fairly small salary so that he doesn't have to pay a large amount in taxes. Yet, he feels that most of us pay too little in taxes.
