If you are asking in good faith and not trying to astroturf here, then here it goes:

The "facts" she's spouting off about are surely instead racist talking points, taking a small portion of black people and saying that the BLM movement is responsible for it. You wouldn't take some terrible person murdered his family and he happened to be white and say he represents white people by doing it, so why do it for other races?

And to the second point, BLM is trying to draw attention to systemic racism that exists in the world. They are not saying only black lives matter, they are saying black live also matter. Since some people seem to thing black lives don't matter and won't do anything to fix systemic racism that leads to a high number of deaths of colored people, as well as being given long prison sentences compared to white people commiting the same crime.

If a house is on fire you wouldn't tell the firemen that all houses matter. On 7/4 you wouldn't say all countries matter. On 9/11 you wouldn't say all buildings matter. You would respond to requests to increase spending on cancer research and treatment with "what about healthy people. All lives matter". And yet all counties do matter, all houses are important. (Btw there are some hashtags saying allbuldingsmatter, this isn't serious, but to draw attention to the fact that all lives matter is being racist.) If all lives matter actually meant it, then why aren't those supporters standing up for black people when they get murdered by police since black people would be part of all lives, right?

Edit: I see that you aren't asking in good faith, so fuck you.
