We are all Guilty.
Now, Mr/Ms Busybody activist person, please tell us what we're supposed to be guilty about this week, so you can feel superior.

What a load of utter rubbish. Slavery was terrible. So was the highland cleareances. So was every war going, etc, etc. There is no point in apolgising for things outside of living memory.

If the prime minister wanted to do something meaningful to apologise for suffering we have caused, then he'd do something about the agricultural subsidies in the West, which cause endless poverty and hunger, or make schools in africa free, or a dozen other things. But those would take real action, and money. Blair is only good at pointless platitudes, and starting wars.
