I don’t think “our history” is what you think it is @RobertJenrick. For starters what makes British history “uniquely” rich? Are other nation’s pasts just bland dull affairs devoid of incident? Must we be “world beating” here too?
The threat to UK statues is wildly exaggerated. Even right wing think tank @Policy_Exchange has only identified 12 specific monuments under discussion, only 3 of which have actually been removed. https://policyexchange.org.uk/publication/history-matters-project/
Compare with this fascinating crowdsourced map of problematic statues, the vast majority of which seem highly likely to remain in place. https://www.toppletheracists.org/?fbclid=IwAR0x7cMCQdw2eoqomoOATYKMvOUT7vYNjaDvlWUNR74P5GP2jdCtCn4U-0c
This is a deliberate tactic as @DavidOlusoga has predicted to distract. https://amp.theguardian.com/commentisfree/2021/jan/03/cancel-culture-is-not-the-preserve-of-the-left-just-ask-our-historians
Maybe the government should spend less time trying to pass laws to protect statues that are not really under threat and more to protect actual people alive now from the racism that is one of the legacies of our “complex”(pass me another euphemism please) history?
