blue lives matter

I saw "police lives matter" a couple of times on Facebook today, so...

Black people started using "Black lives matter" as a slogan, because they felt that a large part of society didn't feel the same way about black people. That a lot of people don't care whether black people live or die.

Then some other people started using "blue lives matter" or "police lives matter" as a direct response to that. Anyone who says "blue lives matter" is stating plainly that police lives are more important than black lives.

More importantly, that police lives and black lives are in direct opposition to each other. Do I need to explain that that is extremely racist?
