“All lives matter.”
It’s wielded to vindicate and justify the one who utters it. It’s used to stomp out the beauty and importance of particularity. It’s invoked to perpetuate American myth. It invalidates and dismisses cries for help and justice. I’ve seen the phrase wound more souls than I can count. I've seen the mindset wound more bodies than I can count.
Of course, “Black Lives Matter” means “Black Lives Matter, Too”. Anyone who’s genuinely listening will catch the implied adverb. Many people aren’t genuinely listening.
“All lives matter” is not true until Black Lives Matter, too.
