There's a great scene in the movie Yankee Doodle Dandy, when a 39-year-old George M. Cohan (played brilliantly by James Cagney) tries to enlist for World War I, only to be told he is too old. He clears space on the floor and does an improvised dance, to great applause. After this he is told he will be of more help to the American cause here (in America) than over there (which, in the corny way you only see in the old Hollywood musicals, leads him to compose the song "Over There").
I think Bruce could do a lot of good over here. Not by speaking out, necessarily, since that would be hypocritical, but by supporting the right side in other ways.
