BLM came about because American cops were shooting lots of black people. It copied by people in the UK.
Police in the UK have shot a total of 10 people so far in the 2020s. https://www.inquest.org.uk/fatal-police-shootings That is considerably fewer than in the US in a single month. Even on a per capita basis it is not even remotely comparable.
No one in the UK (reasonably) worries they will be killed by the police, except people who are actually carrying out an armed crime.
So what I hear is "people think they are living in the US".
> I'm a lot less likely in the UK or the USA to get into a situation where my white skin colour puts my life into danger
In the UK people of any skin colour are not likely to find their skin colour puts their life in danger. The US has about twice as many (the exact numbers do not seem to be available) people killed by police than the UK has total murders. The murder rate and the homicide rate (murder plus legal killings such as in self-defence) is much lower.
I am not white and I have rarely had a serious worry about being subject to violence, never to serious violence, and never been threatened with racially motivated violence.
It makes no sense to lump very different countries together like this.History, culture, and present issues around race are entirely different.
For more on what I think about this, read my blog post about how racism is a different thing in different countries.
