The phrase vs. the movement

I've seen people discount the whole "Black Lives Matter movement" because they disagree with something done by people in some way associated with it, or with some goals of some of the people.

But, see, "Black lives matter", it's a simple phrase. And you don't have to agree with everything said or done by people using that set of 3 words to agree that the lives of Black people matter, and to, thus, say Black lives matter.

People are complicated, and people are varied. It's probably impossible to agree with everything that falls under the "Black Lives Matter" umbrella. Because likely different people have different ideas that conflict. But none of the real or imagined negatives discount the fact that the lives of Black people matter.
