The PHRASE "black lives matter" is true and good. The ORGANIZATION and most of the ideas behind it are BAD and counterproductive.
Among other far-left ideas, the BLM organization promotes the "destruction of the nuclear family" - which would worsen one of the ROOT CAUSES of problems in black-majority communities. It also promotes on its DC chapter's page the complete abolition of law enforcement.

And "systemic racism" is a poorly-defined term, but when often defined as "the police being full of racists", it's completely contrary to what the statistics show.

I'll be avoiding shopping at Walgreen's from now on.
I get it. Self preservation. They can't afford to have yet another store burned to the ground.
Yet apparently they can afford to have half their customer base choose not to shop there anymore.
