The smart ones are not going to say anytning while a career is ongoing. Look at Linda Ronstadt and Alec Baldwin. I boycott both of them now.
As a consumer, I am not that careful about where my money goes as far as political leanings are concerned. I don't partake of much modern entertainment, so I'm really not much of a factor there. I haven't been inside a movie theater since 2001. And I probably only went once that year. But I buy cheap Chinese goods at the local Wal Mart. I buy chicken, charcoal and bbq sauce all summer long without knowing where those companies put their political contributions. I am not much of an activist consumer. Just a hungry one.
