Bonnie Raitt is no Johnny-Come-Lately....she's been around since the no-nukes days and she has ALWAYS been politically active. You know when you go to a Bonnie Raitt concert she will talk politics. She sponsors and donates her receipts to charities. She is up front about it. There is nothing that will stop me from listening to or going to a Bonnie Raitt concert. She is, IMO, the most talented female performer out there and has been for a very long time. And, I respect her for being UP FRONT about her politics.
You're free to subsidize any Marxist socialist or fifth columnist that suits your fancy. No one is stopping you.
