Joan Baez. She put her money where her mouth was throughout the 60's and beyond. She has been consistent with her message of non-violence over the past 30-40 years. She could be immensely wealthy now if she hadn't donated much of her income to causes she fought for. Of all of them, she has been the most punished and shunned. Remember "We Are The World"? Most of the artists iinvolved were a joke when it comes to fighting for causes. Baez wasn't even considered. Love her I do and I take my hat off to her for her unwavering example of looking out for the other guy.
