I'd rather Whole Foods were unionized. I'd rather they sold mayonnaise and cereal that was on par with their produce and meat. I'd rather they didn't charge so damned much. I'd rather a lot of things. But that's just not enough for a boycott.
Really, if I limited my shopping to companies with whose CEOs I agreed on policy grounds, my cupboards would soon be bare and my car would be out of gas. I'd basically just be living off Ben & Jerry's. I don't expect to agree with most CEOs on policies. They're concerned about different things than I am, and they make about a zillion times more than I make. I don't think a store should suffer because its CEO voices his or her opinions.
