Someone made a really astute observation the other day. They said the biggest mistake with the Black Live Matter name is that is should have had a "Too" on the end. Now, people who want to be dismissive of the movement can say things like "All Lives Matter!" and feel like they've made some deep social commentary.
"Black Lives Matter" is meant to remind us that some races are not treated the same as others by those who are supposed to protect EVERYONE.
Unfortunately, too many people fail to realize that.
