Well, I personally think Bono is a massive prat. However you are completely incorrect in your claim that you never hear him 'speak out about Ireland' (what about Ireland, by the way? I assume you mean the Troubles, though it would be nice if you said 'speak out about the Troubles' instead of 'about Ireland', as though the Troubles are the only thing that define Ireland as a country). Here's a quote from him from a live performance of Sunday Bloody Sunday
'And let me tell you somethin'. I've had enough of Irish Americans who haven't been back to their country in twenty or thirty years come up to me and talk about the resistance, the revolution back home...and the glory of the revolution...and the glory of dying for the revolution. Fuck the revolution! They don't talk about the glory of killing for the revolution. What's the glory in taking a man from his bed and gunning him down in front of his wife and his children? Where's the glory in that? Where's the glory in bombing a Remembrance Day parade of old age pensioners, their medals taken out and polished up for the day. Where's the glory in that? To leave them dying or crippled for life or dead under the rubble of a revolution that the majority of the people in my country don't want. No more!'
So yes, he has spoken out about Ireland. I can't speak to the rest of the issues you claim he's had nothing to say about as I haven't clue what he has or hasn't said, but I can this. That live version of SBS always gives me goosebumps.
Yes, there are other bands that have had more to say about the Troubles, eg Stiff Little Fingers in 'Each Dollar A Bullet' or Runnin Riot in 'Right Thru You' (RIP Colin, he was a good friend of my BIL). Then, they are from Belfast, and Bono is not. They were much closer to the situation and better placed to comment on it, IMO.
Feck, I never thought I'd be defending Bono! Oh and Jump, I've been a fan of EODM for years. Their merch manager who sadly died was a friend of a friend who's worked with them for a long time.
