Of course they can have an opinion, but celebrity involvement threatens to turn the protests into the fashionable left wing cause of the second. There's something artificial and glib about rich entertainer's politics - even when I agree with them I shudder when they weigh in on a subject.

They're protesting against inequality of wealth distribution, and a multi millionaire represents said inequality. It's one thing to agree, it's another to be an icon.
