It's statistics, not individuals. And I don't think BLM has anything to do with it other than that it is something that some people apparently find psychologically hard to deal with because they have arranged their lives in such a way that they only have 'whites' in their close environment. You can tell they misunderstood because of how it almost immediately led to 'Blue Lives Matter' and 'All Lives Matter' respectively.

What is statistics?

BLM does have a lot to do with it, the George Floyd wave of protests popularised American racial ideas across Europe.
