For example, the current British PM does not understand why reciting Rudyard Kipling in Myanmar is a problem (https://www.theguardian.com/politics/2017/sep/30/boris-johns...) and he wrote a book elevating his idol Churchill (https://en.wikipedia.org/wiki/The_Churchill_Factor). He really only thinks of Churchill as someone who "saved civilization", while ignoring that Churchill also caused millions of deaths (Bengal famine, etc) – "the Aryan stock is bound to triumph".
By ignoring historical facts and not recognizing that the UK is directly to blame for a lot of death and suffering in India, Africa, and all other places the empire touched, has consequences also today. For example, BLM also made it to the UK, however the situation for black people in the UK is quite different to the US. Probably because Boris ignores lots of historical facts, he doesn't even understand the first thing of BLM UK (https://www.theguardian.com/us-news/2020/jun/08/i-hear-you-b...)
I'm focusing on Boris Johnson here, but his government is largely made up of long time friends from similar backgrounds with shared values.
Ignoring relevant historical context of Alan Turing is an example of larger problem in the current UK government. Gay rights are better today than 1950s, but it's by no means a solved problem. Hate crimes against LGBT are increasing (sexual orientation motivated crimes increasing more than for race and trans is even worse https://assets.publishing.service.gov.uk/government/uploads/...).
