The whole point of debate is to make your argument more convincing that that of the opposing team. Nothing to do with agreeing with it, Vass!!
TBC's got a good idea, here. The Aust govt, in particular the Prime Minister, has refused to say "sorry" to the indigineous people (Australian Aborigines) for their harsh treatment at the hands of the first European settlers. He has incurred the wrath of many groups for this stance. A goggle search should come up with some powerful examples and opinions that young master can use in his speech.
So, the power of the web again helps!

Also, a great debate tip is not to concentrate on the "topic" so much, but the
wording of the "topic": eg what is "retribution" and how do we "pay" people. That kind of logic always goes down well with judges.
