Can we separate pop from politics?

Ed Sheeran says he tries to keep politics off the stage.

But politics gate-crashed his stadium tour anyway -- when the American rapper Macklemore was removed as a support act for delivering a pro-Palestinian speech.

Now Sir Bob Geldof, the man behind Live Aid, says Ed Sheeran's preferred silence isn't political.

Fame, he says, is a currency, and artists get to choose how to spend it

Is he right? Can any artist, whether a musician, a writer, or a painter, stay out of politics? Or is silence itself a kind of political statement too?
