"All lives matter" was invented by alt-right as a propaganda tool. BLM has incomparably deeper meaning.

You sure as hell don’t cry out “SaVe AlL tEh MaMmAls!!eleventyone” when some says “save the whales.” You know full fucking well that no one is saying “ehvatum’s life doesn’t matter” when they say “help the homeless.” Fuck off with your disingenuous bullshit.

Edit: I see in your comments profile that you are frequently disingenuous.

Black lives matter, the term, is a reminder that black lives do indeed matter, because black lives sure seem disposable or a means to an end way too often, imo, lapses in applicable humanism. Its not discounting the lives of anyone else of any other skin color, ethnicity or creed.
